He might be the kindest wonderful person but common decency dictates to inform sexual partners that he has unprotected sex with multiple partners and there is risk to your health and your life. Syphilis and Gonorea aren’t a joke but I also suggest you test for HIV.

I would really stop worrying why he lives off others, doesn’t work and sleeps around. I’d refocus myself on trying to understand why I idolize and romantisize inappropriate partners and how it could be prevented in the future. Please be safe
