I cant squirt!!

When my boyfriend fingers me, it feels AMAZING. Like he curls his fingers up and yeah, its intense. I dont know why, but i cant squirt. Ive done it before a long time ago, i know i can but im just like not doing it. It feels so good, like so so good and i don't hold anything back. I dont know whyyy, he of course wants to make me feel good and i assure him he always does, and he's always like 'I want you to finish babe' but i really try so hard and cant. Do you have any tips??TYIA ❤️💙
