Hi Susan!
My girl and i are going away for the weekend so we were talking of some kinky things to do. ANyway i joked about her using her vibrator on me and she seemed quite interested to try it out. I admit i am excited about it too but when reality kicks in i feel uncomfortable in doing it. Should i just throw caution to the wind and try everything at least once?

thanks!

Sure, why not try it? Just use the same precautions you would for any anal sex. The sex toy should not be used in her vagina after being used inside you without a very thorough wash. Lubrication is essential. Condom on toy recommended for easy clean-up. Be gentle the first time and go slow.

Make sure she understands NOT to lose her grip on that toy if she is actually going to penetrate!! Or get a toy with a flared base that will not enter the anus!! I had many questions my first trip to an "adult" shop and the staff was great- as long as I could spit out the questions- too bad it's so far from where I live. They made it very clear that a toy "lost" in there can be extremely difficult to get back, sometimes medical intervention is necessary! Now THAT would be EMBARASSING!!
I recall a girl on this message board that lost a piece of carrot- see if you can find those posts, she was having a horrible time.
I don't want to scare you, anal play can be wonderful fun and extremely pleasurable, just be really cautious if your just starting. TRUST is of utmost importance-be sure your girlfriend WILL back off if requested.
Good luck and have fun!

Yes, a firm grip or a flared based is essential.
