You have to seriously want it. Or else it will NEVER WORK! The first couple times we tried it, I was in IMMENSE pain. I BAWLED and we couldn't go through with it. You would think it feels like taking a poop, but it doesn't.
If you are one of those people that doesn't have sex during your period, try it then. Get eachother really REALLY turned on. Make sure you are to. Have him tease the outside of your bum. Gets all tingly. Then have him just play with it with no insertion. DON'T FORCE IT! Use lotion or better yet, anal lube. The first time we tried it, we were doggy.
I find doggy degrading and I was NOT in the mood. I think it works best when you are on top. Then YOU can control it you know? I think going faster and harder makes it hurt less (weird I know) but when they go slow it tends to pull and feel like you are really going to poop and it just stings.
So experiment. And do it because YOU want to also, not just because he does.
Oh! And its not the "tight" thing they like, its the whole "forbidden fruit" "I shouldn't do this" is sort of a turn on. Sort of like getting caught having sex lol.
Fact of the matter is, is no matter how much sex you have, your vagina WILL NOT GET BIGGER! If you have kids, thats the only way. If you have bum sex, your anus will stretch and won't return back ALL THE WAY normal. You will still poop normal and everything. But you'll notice every time you have bum sex, it will be easier and easier
