I remember reading a post of someone who was getting partway into their session and ended up counting baseball cards to keep things from ending too soon. Made me laugh cause I've been there. Don't know if others do this, but I've found a good way to get more "endurance" is to whack off some period of time before the session. Sorta takes the edge off and I can go much longer. The trick is to find the right length of time ahead, because you DO want to have sufficient horniness to enjoy your session. Am I the only one that does this sort of thing?
