Squirting, help!!

Katie
I had had a regular sex life before meeting my current boyfriend. I had squirted once or twice but nothing too drastic. 
However, since having sex with my current boyfriend, it happens quite a bit. I orgasm multiple times when we do and more often than not, I soak the sheets. 
He doesn't really say anything about it but sometimes after we get dressed he will say something sarcastic like, "Geeze" or something. Nothing about it being sexy or anything. I always apologize and he just laughs. 
How do I make it stop?? Because I'm really self conscious about it now. Even if it means not having an orgasm during sex.
