Not sure if I am near a female ejaculation?

So, my boyfriend wants to make me squirt, and I'm pretty interested in it as well. I notice that when he fingers me, I DO get that textbook "I have to pee sensation" and so most of the time I make him stop..but if I try to press on, I get this burning sensation..almost like my urethra is irritated from his fingering. I don't know if any "squirters" have experienced this, if it is individual to me, if he's not doing something right..its weird..its like a pain/pleasure mix but I always stop because I'm worried about the pain. It goes away a few minutes after the stimulation stops..but its almost like a UTI kind of pain..like dull, burn. I'm just wondering if any squirters can give me their personal "symptoms" before they ejaculate...maybe its something unique to me or someone else can have some input. I go to my gyno every six months so its not an STD or anything physically abnormal with ME..its just my own curiosity now..and I don't want to continue my quest for female ejaculation if he's going to finger me and puncture my urethra or something lol
