uhh...don't know what to title this...

Courtney🤘🏻 • I just want to cuddle my boyfriend and pet my cat. 👫🐱
My boyfriend lately has wanted me to pee on him during/after sex and I'm really not comfortable with it...
I saw on his phone that he was watching porn where girls pee then like play in it...
Idk it made me so uncomfortable...
Yes we talked about it and he said he thinks it's sexy..and wants me to pee on him...
Does anyone else have this issue? Someone help!!!! 
I don't know what to do...
I want to please him but I just think it's gross....
