Its been a while since I had sex with a man and I'm sexually fustrated

THIS is what 95% of all single men around the world go through, so I can't feel too sorry for you.
I can however recommend you hire a gigolo. Never tried one, don't know how good they are but
I can say that Rob Schneider was pretty funny.

how about a co-worker. did you think about that?

Just head out to the bar and have some drinks with guys! You know most of them are out there looking for what you want.

Well, you've shot down all possibilities, except for that of a male friend. If you have one, think about being with him. Otherwise, you'll just have to do nothing about it and live with it.

Yes you can live...

Masturbate sweety. Get to know yourself sexually that way you can relive your sexual frustration and you won't have to worry about becoming promiscuous.

If you have a friend that your comfortable with there is nothing wrong with being f**k buddies as long as you both know that is all it is.

I once whent 5 years without a boyfriend. It just depends how important meaningless sex is to you.

Vibrators, man. They're amazing. Go for something a bit smaller than your ideally-sized penis, with a clitoral-stim attachment. Between this and your hand, this should help you through the "dry" times. :-)
