blow one off beforehand :p

i would suggest thinking of dead bodies (unless you're into that), gruesome skin disorders, bad spider bites, and a giant isopod on the bed next to you

Well in sex you have some control. You can stop. Or start moving more slowly.
Durinh HJ and BJ it's not a point to last very long, cos other side has nothing from it.

I think that's half the turn off..not being able to stop, so the only option is to take back control, or well, orgasm..

Why should you... the purpose of someone pleasing you is for you to have an orgasm... so I don't see the point in trying to hold... unless you are fast, too fast in which case I would try to think in something else...

A dab of coke right on the head.
Shit'll fix that problem right up.

Unprotected sex leads to pregnancy, so don't do it until you are ready for the consequences.

Wank yourself. When you're about to squirt, don't. Hold it in, accept the pressure. It's called "Stop and Go", Google it. This is resisting orgasm.

You could try and think unsexy thoughts. Tell them to slow down. Tell them to give you 30 second breaks every 5 minutes, that would work well.

Stop and Go -> Just be careful... don't leave it too long. Don't try to stop squirting, or just before its about to come out. This can be harmful, and well, I don't know the technicalities, but it could go back up your dick. Not nice!

Hope this helps a bit

That can be very annoying and disturbing for girls, cos we can't just continue where we stopped, like you guys. So, when you stop, keep stimulating her with your hand or tongue or something.

For all the ones saying to wank beforehand, that's bullshit, it'll totally ruin the HJ/BJ/Sex.

If you have no control you shouldn't worry about cumming quickly, at least in my opinion.
