try doing kiegle(sp?) exercises. if you don't know what this is, it's just basically flexing your vaginal muscles. very easy to do and no one can tell that you're doing it. muscles are supposed to go back to normal after having babies, etc. if this doesn't help, see your doctor for other options.
the v-canal is to open ,not tight at all , no he cant tell when i have orgasm
Do you mean he doesnt feel anything when you have sex? or he just doesnt feel you having an orgasm?
