Is it normal to be nervous to bring kinks up to gf?

Yeah, bringing up fetishes can be a bit nerve wracking, though I'll admit that mine might be a little bit more 'kinky' than what you're into. I have a scat fetish, and it sucks, when I tell women that I like to eat shit a lot of them seemed kind of put off by this. Though, my girlfriend now is okay with it, but I was VERY nervous bringing it up to her the first time.

Very normal to be shy about it. But bringing it up is risky.

Just be all prison gangsta about it and say "bitch, I either want spit on my tit, or shit on my dick"

Tell her now in whatever way you want to. The longer you go without sayibg something, the more difficult it gets. We are in a very open age now, take comfort in that. You need to be in a relationshio where you are not only mentally connected but physically as well. Regret is a bitch. If you cant be your trye self, it may lead you to go looking for it from someone else. Then you become a lying cheating shithole like I am.

I don't see why it wouldn't be normal.

Yeah, just tell her.

I shall not say but I already know who this is.

But about the question -
We all have certain needs in the bedroom. Well like some with down's syndrome have special needs. WAIT WAIT, ok that was tasteless.

Anyways, you must discuss these things with her cause most decent lovers are accommodating. Without at least some of what you want, soon your love life with her will stagnate.

I might add to the above reply this -
When suggesting activities, maybe say, "You know what would make this even better?"

Yes. I was nervous at first with my wife and she is still nervous with me.

You have to say what you're in to tactfully and with subtlety. If you blurt out that you want to tie her up and spank her ass until she submits to your giant cock it's not going to go well and you're just going to turn her off. Say something like "a lot of women like being controlled. Is that what you want?" Or if she likes being dominate you shouldn't say "you want to treat me like your sub bitch? That will make me want to fuck your sexy ass". You should say " I like a strong and dominate woman". She will get the idea if you take it slow, I promise.
