i'd say this......first of all don't think about how hot the chic is or how good it feels...start adding numbers 2+2=4 4+4=8 8+8=16....that's one thing...another is beat it right before you fuk ....a third has already been said...smoke first.....oh yea wear a condom too it makes it almost feelless.....(atleast aafter gettin to fuk someone for 9 months without one it does) ....those tips and you should be able to wear out the chic before you can cumm...lol
