lol each to their own...
I have seen alot more guys being fisted than girls...
double fisting....

lol but I have seen bigger things than 2 fists going up an ass
I'm not really into it though.

But if you like it and you arn't hurting anyone I don't see why you should be put down because of it.....then again I don't suppose you would let all your friends and family know if you were into it..
One of those private things I guess.
