I feel that girls always face the pressure to have a "tight" vagina and such when in fact the vagina is a very durable and stretchy muscle to begin with. If I masturbate, will the guy be able to tell when I have sex for the first time?

I don't think they'll be able to tell. I read somewhere on here that the vagina naturally tightens in excitement during sex, anyway. Unless you're mildly injuring yourself in your masturbation enthusiasm, I don't think you should be getting stretched out or anything.

(Not that I actually have any experience with sex yet, this is just based on what I've read)

Hi gossipgirlxo. Masturbation doesn't permanently change anything physically about your vagina, and neither does sex with a partner. So there would be no way for a future partner to know, unless of course you tell them yourself During arousal, the tissue around the vagina fills with blood so the walls of your vaginal canal can become engorged which may lead to a "tight" feeling, but it's not actually because your vagina is tightening.
