I was reading the thread where everyone was saying how they last for three hours or four hours and I gotta say isn't that kind of overdoing it? I mean for one don't you have other things to do besides sex for a few hours. Also isn't that like dangerous for someone's body to be penetrated for that long? Thirdly why would you wanna have sex for that long? Unless the building feeling is going that whole time and the climax knocks your spine straight isn't it kind of pointless?
