I'm 19 years old and I have a very health sexual appetite with my boyfriend of 6 months but recently I've been horny/aroused but I can't get wet at all and it hurt every time he penetrates me.it hurts when I pee and have blood residues when I do so but I am not on my period or am I getting it anytime soon what could this be?

have you went to the doctor,you are a bit young not to have natural lubrication,could be an infection.thats what it sounds like

I agree, it sounds like an infection. You should go to your doctor asap and get tested.
