Hey everyone, coming to you with a possible concern and/or interesting discussion material. As someone with a larger then average penis, I have come across a concern that I may be able to have help answering here. I find that during intercourse with my partner, after around the 10 minute mark the sensation and sensitivity I have starts to die down quite a bit to the point where I can risk not reaching orgasm what so ever, or to the point where I last an hour long before climaxing. I have a naturally long lasting time with sex, I can easily go on for 30 minutes, but I'm wondering if any of you have had a similar issue. It's almost as if my nerves go a little numb, and as far as I can tell it could either be from me going too hard and too fast thus over-working the nerves; I could be stretching out my partner to the point where he is too loose; or other (?). Any ideas?
