Lately, it seems I'm losing the erection between the fondling and what not. What I mean is, I'll be rock hard when we're first fooling around and it'll be my turn to please her, by the time she gets back to me I'm getting soft again. She said it's not a big deal, but its frustrating to me because I don't remember being like that. I've noticed it to when jerking off. I'm 19 years old and feel like it should be constantly hard like it used to be. But maybe that's me getting older? But I still feel I'm too young. I also quit working out as much down to "Every now and then" which I used to go 3 or 4 days a week. religiously. Could the lack of exercise be a culprit as well or is this just normal and I'm freaking out? I've started my normal work out regimen back up.
