Ohhhh and I almost forgot...you'll probably be advised by some of the whirlwind posters to DUMP him and move on if he can't have multiple orgasms or if you need REAL SATISFACTION perhaps a few "good" men standing by so that you can pull this off!! LMAO....:eek:

I'm a bit confused by this. First of all, does HE want multiple orgasms or
are you the one feeling unsatisfied? Are you saying he comes too fast and you don't get satisfied (premature ejaculation) Perhaps you just need to change up the routine and save his orgasm till you get satisfied? Buddy of mine admitted to useing Viagra once, he said just to see what it would do since he claims he doesn't have a prob with erections. He claims it kept him hard even after he came numerous times but he had a splitting headache the next day. Oh & he said it was definitely sore too!

There are some tantric techniques he can use to sustain an erection and prolong the entire session. But you can induce multiple orgasms in men by ignoring the first orgasm and keep going. If he gets too sensitive however, that will not work so google tantric and see what you can do.
