Guys question about sexting?

Talking to my boyfriend and he just said he wanted to f*** me so hard I go through my period. I was like WTF?????? That's gross. Is this something you would say. He says other stuff too but I'll ask him something hot and he'll reply with the weirdest things. It's more funny than it is sexual. My question to him was what if you came to my place and I was completely naked. I thought he'd be more creative but then he said that gross thing and totally turned me off.
