Turned on when having to pee???

Let me get this straight - I do NOT find pee & other bathroom related stuff sexually appealing in the slightest.

When I have to go to the bathroom it almost feels like there’s pressure on my clit, causing me to almost orgasm, but if I actually did I’d just pee myself.

Is this normal?? I know I didn’t do a good job at explaining it but I don’t know how to any better.

Also I kind of want to tell my boyfriend just because of how it makes me act when I have to hold it and I just want to explain it to him. Any tips on how to without sounding like I have a weird fetish? Lmao
