Another thing that might work is to do some stretches before sex. Try it. Get in a few good yanks in…I dunno, maybe 5 to 10 minutes worth….concentrating pressure about the head so you can desensitize yourself a bit. This might be more of a short term solution. Do some v’s or whatever to provide a little pain. You want to focus on the head.
Lengthen foreplay…. That gets you more relaxed and used to being touched and the longer it lasts and the more frequent it occurs, the more your dick learns that cumming is sort of unpredicktable… Know what I am saying? I think your mind gets used to a sexual routine and your dick knows when it can anticipate some relief. If your having sex within ten minutes of hitting the sheets and your not relaxed….. Take your time, let the heart stop from racing so much… Foreplay is killer anyway…
Also, you have to get your mind off the feeling of being inside her..That’s just going to turn you on more… Think about sitting under a car changing the oil…seriously.. Think about picking up dog shit. It can be really hard and sucks to have to do it, but it helps.
If you’re close to blowing, don’t thrust anymore…stay inside her and do some lite bumps on her clit with your pad. Little movement on your part, gives you some time to catch your breath and keeps her going.. Timing is key…don’t wait too long.
I’ve seen porn stars do this all the time… They will pull out and slap their dick on the girls thigh or clit or?? This sort of knocks the pleasure sensations away with a bit of pain and brings you back down. Do it as often as you need. If your hitting the clit do it lightly and she’ll dig it…
Switching positions often…
I think edging is probably the best way for the long term… You can potentially get over the problem in just a couple weeks. Just like someone mentioned above… You need to train your dick that it’s not going to blow every time it’s touched. Edging is also something good to throw into a PE routine..
