On of the reasons some women like anal is that it effectively massages the back side the uterus. I discovered this years ago while fingering a SO. If if inserted a well lubed finger deep into her anal canal I could feel the back side of he uterus and she would explode with a big orgasm. I have tried this on a number of women over the years and about half have a massive orgasm. Same thing when the penis goes deep into the anal canal.
I believe you are correct. I regularly have anal with my fb and fwb and occasionally with my wife. My fb and fwb enjoy missionary anal as I use a rabbit or other toy to provide the dp experience which provides an endless cycle of orgasms.
Its a power thing. My wife tells me that she gets great satifaction out of having Absolute Control of me while she slides a big dildo in and out of my asshole.
At one time, my wife actually prefered anal over vaginal, she said when my cock stretched her hole enough to slide deep into her ass, the feeling of my cock filling her backdoor felt so good that she would cum almost instantly. I later read that during anal sex, a penis in a womans rectum can stimulate the same group of nerves centered in her clit, making it entirely possible for a woman to orgasm from anal
My ex-wife took to anal sex like a champ! She preferred anal sex over vaginal sex nine times out of ten. She always said the orgasms she experienced were far more intense.
