Sometimes i squirt without cumming?

Hello, so I've always had a very very hard time reaching climax during sex. Even by myself it can take awhile and my bf felt discouraged for a long time because of this.

Occasionally i will squirt, sometimes a lot, during sex and especially while being fingered!! But I'm not cumming? Or at least i dont think i am?

There are times when i wont for months and other times its like every time he fingers me. He is always super proud of himself lol and i don't say anything- not because i want to lie but because it was something he was insecure about for a long time. And i know that it isnt him because he is good at it, its just my body having a hard time.

It's just weird to me that I'd have one without the other? And its really frustrating sometimes because i want to protect his ego but i also want to finish

Does this happen to anyone else? Or does anyone have advice? Thanks 💗
