I'd give Luna007 about 50 thumbs up if I could. It's one of the best things about getting older for women. Sex with no risk of babies.
When I met my future husband, he'd already had a vasectomy. STDs aside (which neither of us had), it was one of the most joyous moments in my entire life.
I cannot describe the freedom I felt about never having to worry about that business. I'm glad I didn't have to wait until my 50's to experience that freedom.
