For the remaining 3 relationships (including the last, my husband), I have tried to use Nuvaring
(a vaginal contraceptive). Each time, after using it for a few months, I had to stop, because of the intense burning and pain inside and out of my vagina. Although the pain seemed to go away after a few months of not using it, the last two relationships ended about then. Scary to think if they were related.
So, beware of Nuvaring!
I can't believe I didn't see the trend.
