Why do I pee when I masturbate??

I know squirting is a thing but is this what women mean by having an orgasm?? What does it look like? Cause for me squirting is my orgasm but I don’t want it to be but I can’t control it!!!

Also I can’t masturbate as much as I want to cause for a week after I have like a really sensitive bladder and I pee when I laugh/sneeze/jump etc. The more often I masturbate the more sensitive it becomes. I dead ass peed my pants at 18 from laughing just a little bit I don’t even hold it control it!!! What do I do??

I only masturbate like once every couple months.

I’m a virgin and I’m 18.

Update: yes I masturbate by clit stimulation and penetration but nothing happens with a dildo. Rubbing my clit is the only thing that makes me “cum” once I squirt I’m satisfied.
