Ok, since I lost a bit over 100 pounds in the last year and a half, I noticed a major difference in vaginal elasticity.

Meaning it's alot tighter. Is this possible from rapid, dramatic weight loss or maybe from cutting out sex by a good 75%?
Do clitoral orgasms which cause the PC muscles to throb (very intensely) make it tighter?

I read a couple places that the more you use it, the tighter it will be, but not for me.

Any help is greatly appreciated, thanx!
