I’m embarrassed but I need help😅

Ok so... when I laugh I piss a lot and I don’t know why. I heard that happens as you age but I’m not even old. I won’t say my exact age but let’s say I’m 14-18. I noticed that it happened about 3 months after I lost my virginity. Idk if that has anything to do with it since piss comes out of a different hole but maybe that info is helpful. If you have any explanations please share. Thanks
