Any tips?

I'd like to become a very quick premature ejaculator. I'm looking to reduce my girlfriends sexual intrest in me enough to cuck me. Any suggestions on how to completely turn myself into a one pump chump?

Watch a lot of porn prior to hooking up. Make sure to beat off but don't bring yourself to cumming. If possible, right befor you are going to have sex, try beating off till your ready to cum, and then go have sex with her. Of course you won't want her to know you're doing that. Make sure to stay off of holy water as it delays ejaculation.

"beat off but don't bring yourself to cumming"

I agree. Also, try and think sexy too; whatever your biggest and hottest sexual turn-on is, fanatsise that it's happening in front of you there and then.

As often as you can in the run to having sex (or not having it I guess), even if you are at work, go to the toilet etc and very gently stroke your hard cock but don't, under any circumstances. let yourself get anyhwere near cumming (look up 'edging' on Google).

Let us know how you get on and that you 'failed' to satisfy your woman.
