why do i only squirt?

this is going to be extremely straightforward if you couldn’t tell by the title already.

I can literally only squirt. this makes sex and penetrative masterbation annoying and messy and such a pain to me personally. my boyfriend likes it but I can tell it is a hassle too trying to stay to one side of the bed, or wherever we are, to prevent everything getting wet. we’ve tried slower sex and different approaches, even along with me trying new things during time to myself, but haven’t figured anything out. any tips or ideas? or am I just broken, haha.
