Whenever I have sex , the first round is very short like less than 2or 1min . I cum very fast .but the second and third round takes time. I want to last longer the first time . What should I do to do that. It effects my orgasms because first orgasms are the best compared to the others and most of the time my girlfriend will not reach climax during the first time so I have to try second and third with a less horny mind and less orgasms. I also cannot go 2 or 3 times daily so I would prefer to extend my first time orgasm longer to have a better experience with my partner
