“My partner used to smoke a lot of marijuana and has now fully quit. I know you can get STDs from sharing and because of that, I’m kind of scared to have any intercourse with him. I asked him if he’d be willing to get checked out but he refused because he claims he has nothing. How can I make sure he really doesn’t have an STD?”
The only way someone can be reassured that they, or their partner, do not have a sexually transmitted infection (STI) is to be tested. If he refuses to be tested, you should not have sex with him. Remember, you can get a STI from oral, anal, and vaginal sex.
Hope this helps.
