careful with that nuva ring shit mang....my girl used to use the patch, and then the pill for a long time and had no problems....but after some close calls of her not remember to take it everyday she decided to switch to this nuva ring you speak of.
shit,,,,it sent her off the fucking rocker....dont know if it was hormone levels caused by the ring but shit,,,for like the first month and a half she drove me crazy, was in ultimate bitch mode, and i wanted to kill her.
anyways, after that things seemed to go back to normal....although, it stays up in there all the time (minus that time of the month) and there were several times where I could feel it when I was finger-blasting her...sort of a weird surprise/feeling....and once or twice felt it while banging her.
