Why does my man always wanna fuck when I’m on my period 😳🤦🏼‍♀️

I swear every time I’m on my period my man is always tryna get it. I have no problem fucking while I’m bleeding but it’s so annoying when I have all the other time not bleeding and he is tired and just wants to sleep 🤦🏼‍♀️ then I start my period and all of a sudden he’s talking dirty to me and feeling me up tryna get some action. Now he knows exactly how to do it cuz he knows what I like and I’m hormonal so of course I have a sex drive like crazy but I feel like this must be a fetish for him or something lol.
