Ethinyl estradiol / etonogestrel
"I have been on NuvaRing for 1 week.  In the past, I've not been able to take hormonal birth control because it zaps my libido and makes orgasm difficult to achieve.  With NuvaRing, since the dosage of hormones is small, I have had no decrease in libido (yeah!) and I'm able to achieve orgasm just as easily as before (woohoo!).  When NuvaRing is in, I can't feel it during sex and neither can my partner. In my book, I give a big thumbs up! I think it's important to recognize that not all birth control works the same for everyone. Most people who think of posting a review, it's because they've had a negative experience. I think you have to try for yourself and see how your body responds."
