When I was in my teens through twenties, I could be had again in next to no time, my first wife would ask to watch while I masturbated. She reckoned she’d not known a guy like me, 2 big cum shots in such quick succession. It takes me longer now !
If a man wants to masturbate after completion of a romp, he should consider doing more for her. If a female masturbates after sex, it usually means he didn't do his job properly
