Some do.

a lot more than you may realise

I can honestly say that I'm not really into it.

I sure as hell do, though I really prefer something else to be there.

Naw, i'd rather have him in there, its much more pleasurable.

Yes very much so. When I was 15 and staring to play around I was with this guy behind a wall and some bushes kissing. Because I had a skirt on he let me sit on his lap so I would not sit on the dirt. He knew I only had on a small pair of panties. I liked this guy a lot and was very tripped that he liked me enough to want to make out. During a long kiss I felt his hand on my butt, under my skirt where my panties where. I didn't mind I was into him. Then a few seconds later also in the middle of a kiss he pushed my pantie aside and pushed his finger a tiny ways in my butt. I was shocked and extremely embarrassed. I had not expected it at all. But I really didn't want to make a scene and it didn't feel terrible so I sort of acted like it was normal except for a huge blush. A few minutes later he broke the kiss and wiggled his finger and asked if I minded. I didn't quite know what to say. I didn't want him to think I was easy or slut or something but I did like it. I couldn't figure out why he chose my butt instead of my crotch. We necked a few more times and he continued to finger me there and I enjoyed it very much and got used to it. I found that a few other boyfriends also had an attraction to my rear. Usually during our first time investigating each others bodies the guy would put his finger there. Some would wait for my ok to go in, others would just take the chance and go up me and see what happened. So since I was 15 or so I've had guys fingering me there and it still happens. I'm glad they do. I love the feeling.

But did you ever have orgasm just by fingering? can a woman?

It's a feeling that you have to get used to, but it feels amazing, and I have orgasmed only by being fingered in the butt.

I do sometimes. It is a completely different sensation and is amazing if the guy is going down on you at the same time. You would be surprised how many girls like it.

Personally, i've never had that done to me, I think I would be more embarrassed than anything. But if it feels good, then I'm sure a lot of women do like it.

omg yes! it feels so amazing to have a finger put up my butt. i have only had 1 guy go down and do it on me. however, i finger my butt while i am fingering myself and it makes it so much more intense. i also get very intense orgasms and usually get very wet. i also use my dildos as well as vibrators and use them up my butt as well. u dont know how good it feels until u try it! and i have had an orgasm just from fingering myself in my butt. it took a while and a few sex toys but i succeeded.

it really depends on the appoach and technique of the one doing the fingering. done properly (tongue first, sufficient lube, simultaneous clitoral stimulation etc.) you can make a woman come like this by accessing her g-spot. almost all of them like it a little, some like it a lot. again it's all in the technique.

Oh G ... I'm getting crazy just thinking of my woman's butt, but she does not like any touch down there (might be she has bad experiences from the past with someone else, or just plain does not really feel anything).

Yes. They really like.

 i wanted to try that with my girlfriend but they keep saying.its nasty and stupid.so i'll maybe not ever get to do that with any girl

No its like having a digger up your butt. Plus the boys finger smells weird after and it rubs off on my clothes.
