i used to have very long ones with my bf but occasional hook ups barely last 10 mins
honestly its all about how into it you're at the moment
if you're worried about your performance just start slow and build up, if you last past 15 mins you will probably be able to go again for round 2 right away
no your friend doesn't need to suck your dick every time you change, but encouragement in one way or the other is a good thing
