haematophilia
Haematophilia in the BDSM world is when someone loves blood so much, they'll do anything to get it. They don't care if it's from a cut, a wound, or just your period. They just want to see it, taste it, and maybe even drink it.

He drank my period blood and said it was the best thing he ever had.
I let him stick a needle in me and he called it a 'love ritual.'
