Is my boyfriend crazy or he really loves me like he says?

Ok so I've been dating my boyfriend for one year and four months, these couple last months he been telling me that he wants me to poop on his dick, the first time he told me I took as a joke but now I think his serious his constantly telling me and I tell him that I don't want to that that's nasty and he said no it's not I love everything about you and I really want you to do it. I'm very confused I don't know if his crazy or he really does love me like he always says, also there was another occasion where we were having sex in the shower and told me that he wanted me to pee on him/ on his dick, I told him I wasn't going to do it  but just like the other Ocassion he constantly tells me to do it. So one day that we were having sex in the shower well I told him I was going to try to pee on him while his dick was in me I seriously tried, I had that sensation of me wanting to pee but I couldnt I don't know if it was because his dick was in me but well it didn't happen and he was kinda sad.
