Kinky Boyfriend

Ok. I'm just going to come out and say it. If you don't want to be grossed out RUN. So me and my boyfriend have been dating for 8 months. I love him to death and we are getting engaged soon. But he is into some really weird ass shit in bed. I haven't been doing the things he has asked me to because it's kinda too much for me.. Like he likes to get peed on and drink it. He likes anal and doesn't care if I shit on him. He also wants me to play with his asshole and eat it out. Is this normal?? Can someone please help. I'm a freaky bitch but not that freaky.. I mean it doesn't even seem freaky more like disgusting.. If anyone has any advice that'd be great! I've never posted on here before lol I just track my periods so I don't really know how this works lol
