Thoughts on period sex?

Do you enjoy it? Do you hate/refuse to do it? Are you just kinda indifferent to it?

I’m curious, because my period started last night, and I feel really fortunate to have a boyfriend who’s more-than-happy to still eat me out, and have sex with me.

I’ve heard/read that period sex is a complete no-no for a lot of people, but I wanna get an idea of how true that actually is.
