Double penetration - dangerous?

my boyfriend recentally bought me a vibrator (which is fantastic) however he's always keen to do double penetration, I.e. insert the vibrator from behind and penetrate me from the front. is this at all dangerous? has anyone else tried this and...

enjoyed it?

No one has really replied to my question. Is this because no one else has tried it?
Are you sure its not dangerous?

I have tried DP with my boyfriend and it was really fun. The important thing is that you are feeling relaxed and he takes his time...when it comes to anal penetration one must not rush but be well lubricated (I.e. saliva, water based gel). If you have not tried anal penetration then I suggest you start off by doing this before going for DP. It helps when your partner plays gently with your anus before penetration (I.e.: gentle rubbing, finger penetration, licking) and also arouses you sexually (oral sex, sex, whatever truns you on). Have fun!

me and my wife just tried it for the first time no less then 4 hours ago.

theres 2 reasons why it could be dangerous
1. the vib. could get stuck up there(it happened to her)

2.cross contamination(transfering ecoli or other bactreia from the anus to the vagina) SO CLEAN THE ANUS WITH AN ENEMA, AND DO NOT PUT IN YOUR COOHIE AFTER ITS BEEN IN YOURANUS WITHOUT DISSENFECTING IT FIRST.

3.BE CARFULL!!!
ITS a lot OF FUN MY WIFE CAME ALL OVER MY BALLS AND IT FELT GRRRRRRRRREEEEEEEEEEAAAAAAAATTTTTTTTTTTTTTTTTTT!!!!!!!!!!!!!!

I did forget about what muthos is talking about...that is the bacteria in your ass is not the same is in your vagina and if your boyfriend and you have anal sex and then vaginal sex there are some rules to fallow: change condoms when going from ass to vagina or clean the pen*s when going from ass to vagina. The reason being that if you don't you will potentialy get a vaginal infection aka yeast infection which aren't any fun at all though they are very easily treated (I.e.:cream from store or prescription from doc). As for the vibrator getting stuck, that's never happenened to me!

I tried it and it was very nice, BUT, make sure to start with a small vibrator or dildo, AND LOTS of lubrication

No! as long as you are clean about it..change condoms after each hole he enters.
but for get the vib..get well lubed and try it with the REAL THINGS!!
my husband and his friend took me to places I have never been before!!

Everyone has made great points here.
1) Use good hygiene
2) Don't go from one spot to another without washing
3) Start off slow, use lots of lube, and stay in control

Also;
You might consider a butt plug instead of a vibrator at first. The come in all sizes (start small), they have a wide base to prevent losing it inside, and they give a feeling of fullness that is wonderful during vaginal penetration.

Have Fun!

oh yes I have tired it me and my husband has three some and one guy goes in my butt and the other one in the other and it feels so good
