When I was young I could go again within a couple minutes… After 30 it was pretty rare… Then in late 40s started having trouble keeping it up for a one time thing, but I figured it was psychological because my then wife didn’t want it (from me) anymore anyway… Then when that ended I took care of things, got a vasectomy and medication that lets me go multiple rounds again, at least in theory… Haven’t gotten to test out the theory yet, other than in my own hands…
