SCORE: How long should sex last?
Penny: It depends on the moment, but most people usually go around 20 minutes. That's good for me.
SCORE: Does that include foreplay?
Penny: No. Basically, I'm talking about the full session of intercourse and sucking dick and eating pussy. Twenty minutes is the standard. But there've been times when I've gone for hours. The only thing is that when I go for a really long time, it tends to swell my pussy. All that rubbing makes me raw, and then I don't want to have sex the next day, and God forbid if you don't want to have sex the next day. So I think a good amount of time is 20 minutes to a half-hour.
