Hey, I understand where your coming from. I felt the same way, I like my high sex drive and I also didn't want that to be altered in any way. I lost 90 lbs since Sept. 07 and that helped my symptoms of PCOS, A TON! I did a Low Glycemic diet... and it helped take away everything bad and I still got to keep the good

Which is the sex drive, I did it 100% natural.. no drugs.
I am currently on Nuva Ring, I just started it 2 weeks ago... if I sense any lack of libido with it.. I'm off right away and I already told my boyfriend that and then it's back to square one. Which I really hope it doesn't because I really like it, it's thoughtless and the side effects have been minimal so far. I have noticed some hair loss while in the shower and this is probably my main concern. I'm hoping it's my body adjusting and everything will be okay w/i a couple months. I am growing out my hair, and that's the last thing I want is to be loosing hair anytime, but especially now. Also my breasts are very tender, so much so that there is NO playing with them for now, and I have to wear a bra while having sex. Sorry if TMI, but I don't hold back much

Anyway so far I feel no difference in my sex drive.
Good luck, let me know if you have questions..
