Hello all, I am a early cummer.. and have trouble getting hard afterwords. I'm 23, my girlfriend is 30. We enjoy our sex and I have been able to make her orgasm on multiple occasions however I cant last more than about 30 seconds the majority of the time. After I cum, I cant get hard for another 30 minutes by then the mood is gone. After I cum I try to keep going so she can reach her orgasm but I get soft and it slips right on out, its getting frustrating for her. I have tried several OTC vitamins for sexual performance and nothing seems to work. Any ideas what can help me last longer, and stay hard?
