I didn't think it was possible but my faith in humanity has gone below zero.

for the love of god tell him differently

Make your boyfriend watch the "Menstruation Orientation" video from Key & Peele. It's basically a couple of guys boisterously telling other guys what periods are like, it's hilarious, and it's one thousand percent true. (For real, if that's what an ****** feels like, I'm taking a vow of chastity because sex just ain't worth it.)

Give him a flesh light made of cardboard, tell him you thought any time he sticks his dick in something he orgasms.

Not that it's my place to question your life choices, but... Why are you dating this idiot?

It sounds like your boyfriend thinks with his little head and not his big one, it also sounds like he lacks compassion

Well, if you have kids with him, you should be the one to talk to them about sex and related subjects.

We need better sex education in schools.

Girls ****** in their butts?

I can't even comprehend your boyfriend's level of stupidity OP. FYL indeed. I hope you straightened him out because his parents, the education system, and his own ability to learn have all failed him terribly.
