Does the female genital organ change in time ?

I know that if a female has lot's of sex her genital part start's getting very loose (the penetration is done more easyly).My questions is if a women that had lot's of (too much) sex in her life and has her genital organ to wide will it get back to being tight if she wouldn't have sex for a long period of time ? (one year or two) ?Does the female genital organ change in time ?
Kegel exercises. Really. For both men and women. If done religiously (and they can be done anywhere) they will keep a woman tight and firm through the whole of her life.

Lots of sex does not change size of vagina, how much is lot of sex I wonder?? What changes the vagina is childbirth . Look at this site :

But I am wondering about two things, first: What is too much sex? Secondly: I doubt it that a man can feel if your vagina is too loose, unless his penis is extremely narrow. The question still needs to be raised as to how he made a comparison to be able to tell that you were 'loose'. I am not sure if you have had any other men, otherwise you would know what size he is compared to other men and would probably have told him him that you could hold a pencil tighter than you can hold him.
Actually, there's a way to prove to yourself how good your muscle control and 'tightness' are. Insert a pencil, sharp end down, into your vagina partway, and try to grip it. If you can manage that then you have absolutely no problems. Your man, however, might have some serious issues that you really don't need him .Maybe he is cheating on you and blames you for being loose (not vaginal but morally).:)
