Aahhh...I see. You were asking my advice in the earlier message. Hehehe sorry, disregard my e-mail.
Well, sir, the only thing I can tell you in that area, is that i've heard of guys thinking really disgusting thoughts before cumming.
See: rotting corpses
maggots eating mouldy foods
baby throw-up
anything that really turns your stomach. As a girl, i've never had issues with cumming too quickly (ah the power of multiple orgasm!) but my guy has told me this little secret when he gets too aroused too quickly.
I read a post earlier on this topic, and one guy had some very good advice as well (with intercourse, not masturbation). When you're about to shoot, don't think "oh this feels soooo good!" but keep thinking (directed at mate): "i'm doing you such a favor, you're gonna get it!" and, strange enough, I see that look in my guy's face every once in a while. He's a freakin' stallion! :)
good luck, and if you think I can help you out some other way, you have my e-mail addy....
Oh and I dont' know about this kegal stuff, but I say,whatever works for you, works for you for a reason...So keep at it.
