I’m an 18 year old athlete in terrific shape Healthy

Patient: I’m an 18 year old athlete in terrific shape. Healthy blood pressure and no physiological problem other than amblyopia. I have no problem getting, or keeping, and erection. I get them quite frequently and they are hard. The problem I am having though is that right when I am about to have sex, the erection goes down. This first happened last week when I lost my virginity. I can be hard for the whole time until Right before I’m about to put on the condom. My girlfriend and I have been together a long time too.
