Hey susan,
I have a question for you, my new girlfriend and I enjoy sex very much and we are trying to get alot of it...you know its finals week and we are just trying to relieve some stress. The problem is that even though I am there mentally my body is starting to lag. I was wondering if there is anything I can eat (i.e. pineapples) or do that can shorten my rebound rate?
Also this is not a question but more of a comment. Lately when I have gotten blowjobs, my face will go numb and sometimes my hands. Have you ever heard of this?

No there is nothing you can do. You need to start enjoying the sexual enjoyment you give your girlfriend as much as you enjoy getting it and those rebound times will be great.

As for your numbness - haven't a clue, but I wouldn't worry about it.

I've heard of the numbness thing...my boyfriend gets it after he has a particularly strong orgasm. He'll say he feels numb/tingly in his lips and fingertips. I have no idea what causes it, but you're not alone.
