JJ - libido was one of the big reasons I wanted to go off the pill, too. I've only had the IUD for about a week, and during that week I've been having my period and cramping so I haven't felt much like fucking, but I'll keep you posted on the libido front. Partly I was horny but afraid to have an orgasm because the nurse said when you have one, the IUD tucks up into the uterus so you can't really feel the string, and I was kind of afraid it would hurt. However, ratbastid helped me prove that fear wrong empirically
