Yeast infection?

Jess

I've never has a yeast infection or uti before. I felt fine earlier, but tonight when my boyfriend and I were having sex, it felt like straight sandpaper it hurt so bad. It wasn't his fault, just felt like my body couldn't get wet at all. Went to the bathroom and showered after and the area downstairs hurts so bad, and looks red. No idea what to do now.

Any help or advice would be great guys!
