TMI!!

My bladder has been irritating the crap out of me. I don't have a UTI, but it hurts almost every day no matter how much I drink water. I don't drink alcohol and the only way I've found here lately to relieve the pain significantly - is to put pressure on the outside of my vagina, while laying on my back. I've cut out caffiene and like I said, don't drink. I'm 22 and soon to be married in a little under 2 months. I haven't had sex in years. My SO  and I have both had sex before, just not with each other. Any ideas ladies?
