Vaginal Air Pumping/Trap

[Everest]

My GF and I are having problems with doggy-style lovemaking positions. When in that position, using long strokes, air gets trap inside. The phenomenon called Vaginal Air Pumping. I try to research it and its been hard get the right info. I looking for ways to stop/prevent it from happening. We tried different lubes and that didnt really help. Also I think Im causing it because of my size, I use XL trojans condoms, so im huge. So its hard for air to escape due to the my size. I tried to go in slow and use my figure to release the air but that cause pain for her and it does not solve the problem because then Im only can use short strokes without letting in the air. If I dont release the air, the pressure is so great that we would have to stop due to the pain she has from the air being pressurized.

Yeah, Im sure its not the penis causing the pain. Every time I go in, air cant escape and when I pull out, we can both hear alot of air escaping. I have to insert my firgure while im in to let the air escape. When I do that we have no problem but air still get in alittle bit. We also bought a dildo to check if size has anything to do with it and it turns out it does. The dildo was smaller allowing it to release the air. We found that Im going in at least a good 5-6in and with a dia. of 1 1/4- 1 1/2, so the seal is very good due to being that size.  

Just this weekend we try using pillows under her stomach and surprisely it work. We dont really know the science behind this. All that we know is that the support helps her and solves the problem.

   Interesting. I am not sure I have heard anything quite like this before. Are you sure it is not the penis causing the pain rather than air pressure? If it is air, why not withdraw the penis every so often and see if that helps. Or, stay shallow in the doggy position and have your long strokes in other positions-- thats not too much of an imposition I think..

   I do think though the pain might be your penis in that position rather than air. Doggie Style really foreshortens the length of the vagina. So the penis gest deeper quicker and almost inevitably with a medium to large penis- it will bang hard against the cervix. This can cause a lot of pain- lubricated or not.

   I think the best technique would be short or shallow strokes in the position and your regular love making technique otherwise. Let me know if that solves the problem- I think it will.
