It may affect your breathing if it's too tight, but I don't see why you couldn't have sex.

Depends on how tight the corset is. Should it hurt? Probably not. The boning might poke at you, but it probably won't be painful. However, if you actually are wearing a cinching corset, it should take away your ability to breathe comfortably. You may pant uncomfortably just because you won't be able to catch your breath. If you want to have sex, I recommend not cinching it as tightly as you normally do.

The only bad thing that has happened while I wear a corset during sex is my boobs will oft fly out and run free, but my boyfriend loves it when that happens. I think it only bothers me because sometimes they swing around and smack me in the face.

No, it shouldn't be a problem. You're boobs might fly out like Blinker said, but that should be it, if that. I've never had a problem wearing a corset during sex.

Thanks for the posts everyone. As for the panting un-uncontrollably, I think my GF would probably like that. Haha.

go to the surgeon and delete some ribbs to feel better! (joking).. just choose the right size for you and everything will be fine...

My wife can wear hers during sex, but she doesn't have quite as much mobility. But like others have said, maybe just wear it looser.

Never tried. Sounds sexy but I like to be totally flexible and free to move without having the bones in the corset being a hindrance.

I have never tried it but I would say no to doing it with one on.
