WHAT THE ACTUAL @&!?$!!!

So this has bothered me for a while, and now I want to know if I'm alone in this or not.
MY BOYFRIEND WANTS TO PEE ON ME!
Now, I don't know if he is joking or not, but on more than FIVE occasions, mostly while we are showering together, my boyfriend always makes comments on how he wants to pee on me. We'd be talking and he'd suddenly be like, "what if I peed in you during anal?" Or We'd be showering and he'd comment on how he had to take a piss and when I tell him I'm a big girl, just aim for the drain, he'd say, "or what if I just go on you?" I usually just laugh him off and redirect our convo, but he mentioned it again the other day. This is so GROSS to me and there's no way I'd ever partake in that, but do you guys think he's actually being serious and trying to hint at something? And is he strange, or have any of you ladies had this problem?
