I have the opposite issue, I tend to find the girl's attractiveness and my interest increases as she get naked. After I orgasm the high can last a good hour to 90 minutes afterwards. I grab a coffee, maybe something to eat to compose myself afterwards.
I always want to continue. Never lose interest in them and/or roll over and go to sleep.
Sometimes I remain fairly hard inside her and can carry on for a little while, although it's a struggle what with the chemicals / endorphins or whatever your body is producing.
Generally though, if I have come quicker than I would have liked, I'll concentrate on the girl's pleasure some more and this gives me some recovery time.
