Virgins can be a bit of a thrill, gives you that "conquistador" kinda feeling. It is mostly mental though, tightness in their unit is genetic...
However, like any muscle in the body, the PC muscle will soften up and get looser with age. That’s why some older chicks can feel a bit looser.
Women who have children should not experience any permanent enlargement of their cooch... Some women that get cut in order to make birth easier can get even tighter after the doctor has thrown a few stitches down there and it heals up.
If any ladies here want to get their pussy tight here is what you must do: Exercise your PC muscles everyday, over time it will get much stronger and tighter. If you take some Anavar and do your PC exercises then the progress will come much quicker.
