How long does it take?

Why is it some girls viginas are loose and some girls viginas are so tight? does it realy matter what size partner she has been with? How long does someone have to be with a partner before they start to strech there vigina.....?

Stretching depends on:

1) The girl's personal anatomy. Some are taller and bigger in general, and feel 'looser' compared to small girls
2) Experience - a girl who recently lost her virginity, or hasn't yet, will logically be tighter than one who has been penetrated for years. It's a muscle, it stretches from use. How long it takes to stretch and how much - now that depends on the girl and on what she's been doing (and with whom)
3) Exercise - the muscles in and around the vagina can be strengthened with kegel exercises, which is a way for girls to 'tighten up'
4) Dildos - if the girl has been playing around with large dildos, obviously she will have stretched more
5) Partner size - yes, size matters in terms of stretching the girl. My boyfriend is black (yeah the myths are true) and just for the first month I stretched more than I had ever before. I didn't see him for two weeks over Christmas break though, and when we came back I had tightened again, which proves the point that muscle is elastic and can both stretch and tighten. And tends to go back if you leave it alone for a while.

Bottom line - many reasons to stretch, but there are ways to tighten up again too, if the girl takes a break and allows her muscles to restore their initial condition, or if she does those exercises.
