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? Is it already "tight" again...Does that even make sense!?? PLEASE HELP!!
