A new deep-dive gas guard

A dive-chick having a DCS attack

Decompression sickness, DCS: Adolph has a young dive facility attendant who went up to his summer place on Lake Tahoe to bring back some dive equipment to the training facility. It’s about a 500 mile trip one way – his place is on the California side south of Truckee - so they were going to stay over night. The lake is at an average surface elevation of 6,225ft, about 4,000 feet higher than Vegas, and the dive-chick wasn’t paying attention to her nitrogen loading. She had dived to depth the evening before she and her boyfriend drove his truck to Tahoe. They were going to have a swim in Adolph’s indoor-outdoor pool so she changed into her wetsuit and went out on the dock to get the equipment off his boat. She hadn’t been feeling well on the drive up and had an attack of DCS and collapsed before she got to the boat. This is an example of DCS from diving before moving to altitude. If the diver moves to a high-altitude location on land immediately after scuba diving s/he may be at risk of DCS. With this dive-chick she is young, thin, and healthy and so a +4,000 change in elevation shouldn’t have been much additional risk, but she was on the edge of her nitrogen limit and some people are more likely to be affected by DCS than others and she was one of them. Her BF dialed 911 and an EMT crew were there in about half an hour. Fortunately there is a hyperbaric chamber facility in Reno which was only about 70 miles away East on I80. She’s doing well and will probably make a complete recovery, but she won’t be able to be an active diver again.

Reflexions latex diaphragms as deep-dive gas guards: I have been working with my Gyn to try the Reflexions latex flat spring diaphragm as an effective gas guard at depths below 30 feet. Returning readers will remember that most diaphragms, the ones with arching spring and coil spring rims, should not be used for contraception or as a gas guard if the wearer intends to dive below 30 feet. That’s because the arcing spring and coil spring designs have air pockets in the rims that cause the rims to distort at pressure below 2 atmospheres, 33 feet. The much more seldom prescribed flat spring rim has no voids in the rim that will make it sensitive to distortion from pressure below 33 feet. I’ve been testing the flat spring diaphragm by using it as a gas guard (worn over my primary protection, an Oves cap) at the bottom of the pit about 65 feet below the surface and it has worked very well. The pit is 68 feet deep, but to prevent being rammed into the bottom while penetrated I like to be taken a few feet off the bottom. A few more successful tests and I will have the confidence to use a Reflexions during my 2 to 3 day period – when I can’t wear an Oves - so I can have deep dive-sex on any day during my cycle. The next step was to test Reflexions at 130 and with Adolph as my partner. I was sure it should work at that depth as well as it does at a depth of 65 feet. Talk about a breakthrough in deep dive-sex! And of course almost any woman can be fitted for a Reflexions so she can have effective .protection for deep dive-sex regardless of where she is in her cycle which is so awesome!

I had planned to wait until Elke was through with her visit to Adolph’s but she developed a sinus infection and a migraine headache and has to lie still in a darkened room and can’t dive for a few days so Adolph asked if I wanted to try my gas guard tests with Reflexions at 130 feet this weekend. That worked well with me since Jacques is in Europe on business so I had some free time. Adolph is fun to be with if you are careful to double check your equipment and enjoy risk taking. He’s way kinky and can be very sadistic, but he’s not so bad when he is with me as a partner. However, if he can be somewhere else when his guest’s are using diving equipment an accident seems to happen. His women guests will almost certainly have a major equipment failure of some sort and his students have multiple equipment failures from which they learn to survive, or not.

Breathing gas: We decided to do the 130 foot test breathing regular air (21% oxygen) rather than Nitrox because at that depth with higher concentrations of oxygen there is a greater risk of oxygen toxicity and 130 feet is below the safety level of both Nitrox I and II mixes contain 32% and 36% oxygen, which have maximum operating depths of 110 ft and 95 ft respectively. So we took the penalty in the form of a long decompression stop on our ascent. Even so we wore Ocean Reef FFMs so if we did have an OT seizure we wouldn’t have to worry about losing a regular when unconscious. At 130 feet we were both feeling the effects of nitrogen narcosis, but as long as we concentrated on having sex we were safe enough. Afterward we ascended to a bit above 100 feet to enjoy the afterglow w/o either of us doing something stupid while narced. Before someone asks why we didn’t use Trimix again the answer is that Helium conducts heat 5 times faster than air and so it can chill divers who then need thermal protection (When we used Trimix a few days ago we were in wetsuits in relatively warm water.) not something I wanted to contend with during dive-sex device testing. The facilities water heaters and circulators have been running full time and the water was a uniform 78° F, delightful for dive-sex because both partners expend a lot of energy. Adolph wore a Speedo slingshot and I wore one of my custom made Gottex yellow thong bikinis under my BCD. The Gottex suit was almost a mistake since I don’t like to lose one of them and I didn’t want to dive to the bottom to retrieve it if it fell away unnoticed. So after he undressed me I wedged the suit under the first stage regulator fitting on my tank. And afterward it wasn’t as though the deco stop was wasted time. I had Adolph take me again while I was tethered by 2 ankle leashes to wall mounted D-rings at a depth of 20 feet. He penetrated me in Missionary (I was tethered in a split) so I could watch him moving in and out of me. He is quirky, but he was very considerate of me and gave me a massive G-spot orgasm before he spewed hundreds of millions of sperm against the stretchy latex membrane of my gas guard.

130 foot depth test results: After we decompressed and rested I Kegeled then douched with clean water to get the semen out of me so that as I removed the Reflexions the dome wouldn’t pick up any semen from my vaginal walls. I had worn the diaphragm dry (without spermicide) and was double bagged, with an Oves sucking on my cervix so if the diaphragm leaked I wouldn’t be at risk, and was delighted to find that with the exception of a little natural lube the dome was empty. There was no leakage of any sort water or semen from three very intense encounters with a lot of cervical thrusting two of which were below 130 feet. I realize a single test dive isn’t definitive, but I see no reason why the results shouldn’t be repeatable with a properly fitted and positioned flat spring diaphragm.

Super Bowl XLIV (44) 02-07-2010: A friend asked what I will be doing on Super Bowl Sunday. At the casino there will be the usual private parties - I think we are nearly at capacity - and the screens in the bars will be showing SB XLIV, but I'm using the occasion as an opportunity to get away from work. I’m having a get-together at my place similar to the one I had at Thanksgiving. I’m thinking the guests will be: Taryn & Chuck, Cyndi & Chris, Anya & Robin, Shelly & Jeff, Marie-Claude & Pirate, Diané & Peter and Jacques & me. And, perhaps Elke and Adolph if they get along well and Elke can stay another few days. I’ve also invited Cyndi’s mom Fiona and her escort of choice – on Thanksgiving it was the sponge worthy Maj. Colin Tree – but I’m not sure she can join us if congress is in session. The menu will be primarily barbecue but steaks and chicken will be available cooked by casino kitchen and wait staff while off duty so they can make some extra money. The pit and swimming pools will be open for qualified divers so I’m hoping to have sex with Pirate and Chris neither of whom I’ve been with intimately since Thanksgiving. I’ll be CD24 then and still have Oves sucking on my cervix so I will be able to have dive-sex at any depth.
