Sensation of Peeing (TMI-ish I guess)

I'm 22, just so you all know and Ive never had a child. When my SO and I are having sex doggy style, I feel like I'm about to pee everywhere. This only started happening about a month ago. I know when a guy hits the G-spot it can feel like you have to pee, but I'm used to that sensation, it's normal to me. This is so much worse. I don't feel like I'm really old enough I lose control of my bladder. Just wondering if this happens to anyone else and if I need to just learn to ignore it lol
