I'm scared I might have something

It's really ruining my life, ever since I got with my ex things just started to go downhill. He treated me horribly and would verbally abuse me and emotionally repress me. He just wanted sex and lied to me and made me feel really terrible from the things he'd say and do to me. But anyways, I'm only 18 and he's 37, he told me 27 when I first met him through grindr though. While with him, he got me addicted to meth, forced to have sex even when I didn't want to and was feeling really horrible, constantly made fun of me especially in situations with other people, and was just horrible to me he put me through so much shit and didn't even care how it all affected me. I can't trust him, I asked him if he was clean he said he was. The next time I met him which was about 7 months later he said he was still clean, then he asked me to be in a relationship with him. I said ok. He's homeless, he's also addicted and was in prison for years, I believe he has many sexual partners since I seen him constantly talking to other guys and girls and sending nudes and making plans. I was hurt and I hate myself for staying him through it all. Anyways I was with him when I started to have a burning sensation and itching and it'd hurt to pee. There was small drops of blood sometimes at the end. I also had three kinda clearish white big like warts on my butt and three on my fingers. They just felt sore and I didn't notice till later one night with him in a hotel room. I was with him that whole week.
