.. Squirting..

So my boyfriend tries to get my to squirt but it never happens like I feel like it's about to happen but I freak out because I feel like I have to pee. I know that's how you're supposed to feel but I just can't relax. . Have any of you squirted before? I know this is a weird question 😓 but i was just wondrring if any of you have and if you have any tips that might help me? I want to do it I just don't know how to relax enough..
