I don't want my gf to talk about me much to her friends?

I'm a very secretive/private person. I'm not suspicious, and I really have nothing in particular to hide, but the idea of my gf telling her friends (people who I don't even know very well) some intimate and personal details about me is kind of upsetting.

Some girls will talk about how good/bad their bf is in bed and the size of his penis, and I'm like "wtf?". Sex is very private. I might as well have it in public if my gf is going to tell her friends every conceivable detail about it. I don't want her friends to know more about me than the government does already. (I hate this new surveillance trend too, btw)

Am I alone in this?

It doesn't seem like she'd be the kind of girl who'd do this, but it still worries me.

Ha! Good luck with that one. LOL.

Its perfectly normal for girls to discuss this. Get used to it.

I'm not so sure people were always this open about their sex life before. It might be even very recent when it was normalized.

If don't like the idea of it, how can I voice this? I don't expect her to not say ANYTHING about me, but not EVERYTHING. I'm pretty sure my gf would be very upset and probably dump me if I sent nudes of her to my friends, but for some reason it's okay for them to talk about my sex life or other really personal stuff?

Not wanting details about your sex life to leak out is a reasonable request. But if your demand for privacy stretches as far as not wanting her friends to know if you two go on a nice dinner or a trip then that's a bit too much.

Yeah, I don't think that would be unreasonable. Prior to this, I never had a gf. I feel so open and exposed- and vulnerable.
