(NSFW) A question about birth control specifics...

Do birth control statistics (like, “the pill is 99% effective when used correctly”) assume that the guy is cumming inside of you? Or, in a condom/not inside of you? It has got to be one or the other right?

And I guess I’d also like to ask a personal level, women, do you let dudes cum inside you? Does it depend who it is, how long you’ve known them, or do you never, or do you always?

I personally never have…I’ve only had a few partners and I wasn’t on the pill at first so we always used condoms, and he came “inside” me then but that’s different. And then once I was on the pill, the guy would just cum on my stomach, he never really inquired about anything more. So now, the guy I’m seeing asked if he could cum inside me, and I got all flustered! I was like “uh uh uh uh uh…no…I don’t think so…well. maybe. not yet.” LOL but I guess that just made me think that I don’t really have a reason for not letting him, I just got some weird scary pregnancy thoughts going on up in my head.

So please share your input. I really don’t know what the norm is here, and I’m really curious.
