I've done it twice in my 44 years of existance.
Funny part is, my brother who has a much lesser 'sleeping around' count than me has done it with about 7 odd women. Not saying that all men who does anal with their women have got small thingies but my brother is not really blessed. Sounds terrible I know.
Therefore I have actually asked myself if his 'hit-rate' is not because of him being smaller ?
My wife and I have been together for the last 18 years and I have played around there with the nip (half of my fingernail) of my finger but she quickly lets me know when I go to far. She's not keen on it at all so I respect that.
I guess I am more experimental than her but the reality is that no-one, but no-one comes close to my but (lol) so therefore I have to abide to her saying no.
On a comical note:
"why does a women have a butt-hole ?"
it's their spare channel !
"what do you call the skin between a woman's vagina and her anus ?"
A tjommie, it keeps you out of the shit !
interesting answer you posted
you asked why does a woman have a butt hole
i don't think it's there to get your dick in it there is a proper place for dicks
( vagina)
there are alot of harms from anal sex
such as:
1/ psychological disorders for women that doing it and also gays
2/ herbs, syphilis and most common gonorrhea
3/ rectal cancer
4/ immune system disorder and that's because when the inner walls of the anus absorb the cum it goes to blood stream and it's affect immune system
5/ some wounds and rectal fibrosis
all we are know tylla wynn i heard that she can't take a shit without an enema because of anal sex
and also belladonna has herbs because of that
it may happen alot of these problems and may not happen any one
and it only comes with long term of anal sex
you can ask a reliable doctor about that
