They say a Guy reaches his sexual peak in his teens, but I've never been hornier in my life then right Now and I've been out of my teens for 36yrs, hence making up for lost time in every department.
If I'm really horny and afraid I may cum too soon, I'll take care of myself before I get with a partner, so if it makes it "harder" to cum, then is'nt that a good thing for your partner? (assuming she actually enjoys sex)
Why not jrk-off on her just to get things started. They always like that.
I've heard that if you really want to make your lady friend "light up", you just have to wipe your d**k off on her bedroom drapes after doing the deed. They apparently "luv it."
