tightness

Did my previous masturbation de-virginize me?

asks:
I am 15 and when I was 14 I started becoming very interested in masturbating. I actually used objects and penetrated them inside my vagina. After a while i realized how stupid I was being so I stopped with the masturbating. I've been dating my boyfriend for about 4 months and we are so comfortable with each other....

A few choice words about "tightness"

asks:
How long does it take for the "vagina opening" to get tight again after sex? A few days, a week? Do PC muscle exercises help? Say I hadn't had sex for about 5 months and then just had sex about a week ago, am I "looser" now then I would've been if I didn't have sex at all? And if so, how do I make it tight again and how long does it take?...
