Here's the exact scenario:
Was meeting her for dinner at a place about two blocks away from my apartment. So I popped a pill literally a minute before I met up with her.
During the walk home from dinner - maybe about 75 minutes later - we were holding hands, and I felt some slight activity in my pants even during the walk home. (This is highly unusual for me)
Got into my apartment, and had her on the bed about two minutes later. Started kissing passionately... and after a couple of minutes of that, I was fully hard.
I was harder than usual so I actually had time to get the condom on, keep it up, and put it in her. (This part has been a struggle for me)
Sex with condom lasted maybe 25-30 minutes (not sure).
I wasn't able to get off with the condom on, and in fact getting off in general was difficult for me, but hopefully that's something to work on. I did eventually get off but the circumstances for that were not optimal (helping myself).
We cuddled and watch TV for about an hour.
After about an hour, we slipped into bed again... and started making out again, and I got hard again. It may not have been quite as hard as before, but it was still good enough to get inside her again and have a second go. I got her off again, but this time I didn't get off myself.
After she left, the next day I able to easily get a full-on erection to the thought of her just by touching myself a little.
