Pee sex ?

Does anyone else fanticize of their boyfriend or just s guy in general peeling inside of them during sex ? I find myself watching porn of this action and I always get beyond turned on from it and really want to do it . Yes it sounds gross but first of all it would be with the guy I've been with for over 2 years and it's not the fact that it's pee but that it would be a warm nice like flowing sensation into my vagina . Also, I feel it would be great because it's getting closer and showing that you're more than comfortable with that person. Is it just me who wishes to do this ? Also , how do I go about finding out if my SO would be even willing to do this ? If I ask and he thinks it's nasty or grossed out I will be embarrassed for life !
