as your about to come take your cock and slap it a few times pretty hard.

ive seen pornstars do it. but ive offically tested it out and its very effective.

Shut the fuck up, acolyte.

shut the fuck up cousin fucker

I usually just pull my foreskin up really hard and then I don't cum. I have no idea why that works though.

i usually just cum. and then get hard a little bit later.

Don't flex your PC muscle.

Cut off your penis. That'll stop you from cumming. Forever.

Ahahaha, if I was fucking a guy and he pulled out to slap his dick I'd shit myself laughing.

Practice, during sex and masturbation you have to feel for the moment or it'll hurt if you stop. Thinking unsexy thoughts helps. Mostly though it's controlled by your breathing and the rythm you got going, if it feels too good switch it up a bit. I've been able to go over an hour using this method but honestly for most females they're good with 10-25 minutes anything else just leads to soreness even if you use tons of lube. Of course most guys are full of ego so they think if they can go for really long they must be pleasing the girl.

Slapping your penis sounds really really dumb and isn't anything i've ever seen or heard of. Something tells me you're trying to get someone here to be stupid enough to actually try this.

Yeah, tru dat. Most chicks aren't expecting a 3 hour sex marathon, and it would actually be pretty unpleasant for them. As long as those 15-20 minutes are good they'll be happy.

Plus...sex is supposed to be fun and thinking of dead babies or fat aunts isn't my idea of fun. Just enjoy it and if you do it too soon, do it again.
