Refraining from sex ?

No joke, my boyfriend won’t have sex with me until I’m three days “clean” from my period. Meaning, I have to go atleast 3 days with no blood before we have sex. I feel like that is literally physco and it’s so annoying. I got off my period two days ago, I showered and shaved this morning, put on my cutest “sexy” outfit and jumped into bed with him and he literally told me, “let’s wait till you’re 3 days clean” like tf!?! Would anyone else be annoyed? Does your partner do the same things? Ughhh it’s so annoying.
