What to do?

I posted not too long ago but after me and my bf went camping, he came home with a really bad itch on his penis. Turns out he DOES have insurance through his dad and we got all of the information to go to a doctor. I went out of my way to find him a provider that his insurance covers and found a doctor that’s accepting new patients. I am asking him to go to the doctors and figure out why his penis has been itching and has a rash and he just straight up told me no. He is not going to the doctor and I’m stressing too much about it apparently. He said that if he felt it was a big deal he’d go but he said it just itches a little and the rash will go away. Idk bc I refuse to have sex until we figure out what this is, bc he shouldn’t be itching and red... what do I do???
