Tmi...

I've always loved it when my BF fingered me.... I always climax... But I'm afraid of peeing on him.... When he rubs me, I kind of pee and get embarrassed..... Here's what I'm wondering,,,, if I wanna make MYSELF squirt, what are techniques to doing so?? I'm new to this... I've always used a vibrating toothbrush and I get really turned on and as I feel like I'm ready to like squirt I just stop coz I can't take it.... What do I do??
