Ok, so here's my situation. I met a female half of a swinging couple who is not only very attractive but also really personable as well. I'm definitely attracted to her. Her and her husband's fantasy is to watch her enjoying a hung guy aka me . I've never really done this before but the idea of it does get me hot. Also he wants to videotape it which is ok with me as well. So I went over to a few days ago to play with her in front of him while he taped and watched. I don't know if it was nerves or what but I couldn't keep my erection. This has never really happened to me before and I'm not sure what to do. I'm young (mid's 20s) and can stay hard during masturbation so I know it's not a physical issue...or at least is physically possible. What should I do? I was thinking of trying yohimbie. Do any other lpsg'ers have suggestions or input? Viagra maybe?
