Im a 22 year old guy and have some trouble in bed with my gf. I'll get hard really early, when we start making out and stuff. it's hard on its own, with neither me or my gf touching it. but then we fool around and she gets aroused, like 15 minutes after, and I've started to lose the erection. once this happens, it's like half an hour before I can get it up again.
Is it normal to lose a boner after like 15 minutes if she isn't playing with it? and is it normal to have to wait 30 min or so before you can get another one?
I've been doing kegel stuff for men, and I feel like it's harder... shoud I keep on doing these so my erections last longer? Ive also tried to mentally calm myself down so I don't get a hardon so fast, but that didn't work. this hasn't happened before, and now I'm just worreid each time. Thoughts?
