A woman has a right to say no at any point during sex (so do men). Even if you have been having sex for an hour, if she says stop, you have to stop. There are no exceptions to this rule. It may not seem fair to some men, but that’s tough. Sometimes you don’t get to do whatever the fuck you want. This would be one of those times. So suck it up, tuck your penis back in your shorts, and get the fuck out. Either that or you can expect that prison scenario to be your next stop.
