So something happened a few months back and I cant explain it. My fiance and I have been together for a couple years now and have always had great sex, but a few months back in the middle of a stressful period i had a few instances of finishing before i had intended to, which has never been a problem before. Since then however she seems tighter then ever to me and every time i peak quicker then her. I am fairly certain at this point this is all mental but I dont know what to do to shake myself of the increasingly discouraging situation. She's patient and understanding, but I want to satisfy her like I know that I can. I am def. above average and she's very petite, so I know we're a tight fit, but that was never an issue before. How do I get past my mental block? Thanks for listening.
