I've met both women and men with higher / lower sex drives than me and based on my own experience I'm inclined to believe that while men go into overdrive faster they have no monopoly on being obsessed with sex.

I consider mine to be high; that being said, I know of two women who have higher drives than my own.

I also know plenty of men who've said no to sex because it wasn't the right time / didn't feel right / wasn't enough.

Unfortunately, I've been in this position a lot of late...
