most guys can't keep it up after, and that's fine, there are plenty of other things you can do while its still in the on-deck circle waiting for another at bat. i remember one guy who could stay hard, but couldn't ejaculate again no matter what i did - he would end up a red, sore, chafed, pulp when we were done (how many guys just crossed their legs and groaned when they read this?) but he's still be hard, so i could still use him for my purposes, i found that fairly useful...
