This is probably a stupid question, but it's one my wife raised a while back and I thought that I could ask it here. She thinks it would be incredibly hot if we could find a *safe* way for me to thrust rapidly into her ass, then her pussy, and back again—alternating back and forth, one stroke per hole. As far as I know, this is impossible because of the serious risk of bacterial transfer. Still, I told her I'd look into it.

Everything I've read so far online appears to confirm my suspicions that this is dangerous to her health. It seems like the closest thing we could realistically do is to have me wear a condom in her ass for several minutes before taking it off for vaginal sex, then putting a new one on for anal.

Can anyone confirm or deny? If it *is* possible to have safe sex in both orifices, how does one go about protecting the woman from infection? Thanks. less

It's virtually impossible to properly insert a female condom into your butt. There's an internal ring, and it doesn't go in properly, plus unless you use a really well lubed dildo, it's nearly impossible to get the condom IN all the way. Even then, it's very difficult and can turn inside out.

Because of the public bone when used vaginally, the female condom is "stuck" in place until removed, (the inner ring goes behind the public bone like the ring of a diaphragm) but with an anus, there's no structure to hold the condom in place.

IMO, it's better to just start with vaginal, lube up and then move to anal and stay there, unless you both wash up really well. I don't see a way of rapidly going from butt to vagina and back again without risking serious infection.

Just because one person had an anecdote where "nothing happened" doesn't eradicate the evidence of how dangerous going from butt to vagina really is. EVEN with "good cleaning" the anus and rectum still have bacteria that is dangerous to the vagina.

Using a toy for one orifice and a penis for the other is really the only safe way. less
