peeing during orgasm???!

Ok so basically i find that whenever my vagina is stimulated by the clitorus (through mastubarion using a vibrator) it gets so intense and I feel as though I'm about to orgasm but when I feel like I'm orgasming, liquid comes out and at first I just thought it was normal but it looks and smells like urine, like a lot. When I have sex with my boyfriend this doesn't happen and only happens during clitoral stimulation but I'm embaresed for my boyfriend to ever use a vibrator or stimulate my clitorus in case I wee on him!! Does anyone else have this problem!? I know orgasms often feel like your about to urinate but this most defiantly smells and looks like urine, but even if I go to the toilet before hand it doesn't make a difference? Help please😭
