I have been using nuvaring for about four months now. The first month I experienced frequent, almost daily headaches and almost changed my mind about using it. After the first month that went away though. I love it now. It hasn't made a difference to me as far as sex, my partner says he can feel it during sex but it doesn't bother him. I love being able to control my period with it. Allthough the first month was not fun with the headaches, I am glad I decided to give it another go. I have also lost about 15 pounds since I have been on it. The only concern that I have and have not been able to find on any websites is what is it doing to my boyfriend? It is continuasly releasing hormones. That would include while we are having sex I am assuming. Are there hormones being absorbed by him? And if so what could happen to him as a result?
