Sex and urine

I wrote ohter day about my man being a diaper lover and how should i feel about it as far as it threatening our relationship. thus far we incorperated it by him peeing on/in me. never had it in me so was odd but he was super turned on. Now, i am happy to have him happy doing something kinky with me instead of a diaper/object and not hiding it. i feel we got closer (obviously lol) but does anyone think there is another way to incorperate this before i end up with infection lol and anyone else besides me think there is more kink waiting to be revealed? is this normal. are we normal lol
