These days something strange happened and I would like to get some answers please because I'm confused. Me and my girlfriend were playing around, touching each other and doing sexual things in public places so, logically, we couldn't had sex. I knew that she wanted it too but we had to wait more than an hour until we could be alone and have sex. We already were exited so we couldn't stop and continued sexually playing for that hour. Of course I've had a boner all that time and a lot of pre cum came out. After all other people left I went and had a piss, there I noticed all the pre cum on my penis. When I returned back we immediately started doing sex, but I could not finish. This is my first time with my girlfriend being unable to get an erection and first time I had some much pre cum. I felt embarrassed and I think she's upset now because of that. I want to know if there is something that I could do to reduce the amount of the pre cum to avoid situations like this? Or there could be a serious erectile dysfunction?
