As someone who has sex on a regular basis with (one) woman who has an IUD, my experience has been that it has no impact whatsoever if installed properly. The uterus (where an IUD lives, naturally) is not typically involved in the act of sex.

I figured as much. You'll have to ask nekitamo what he was on about.

I've never noticed the IUD, but I did notice the NuvaRing (it wasn't bad or obtrusive, just "uh, wtf is that?")
