Pretty hard not to, when about 80% of people have HPV.

My base reaction would be that I would not, as I do not have an STI (I test frequently, regardless of sexual activity). I might consider it if I believe we may be exceptionally compatible (emotionally, goals, etc), the type of illness, AND we spend enough time for me to see that they are managing it well enough on their own that I can be confident they are minimizing my risk. While zero risk is not achievable (even in a monogamous relationship with a STI free partner), if they are managing their half of the equation and I’m managing mine, then that shows they are a partner who cares enough to protect me. I know that many with STIs may find that frustrating and view it as part of the stigma they face, but it isn’t about them. As an individual with no infections, I’d ideally like to keep it that way.

Preferrably not, particularly more severe ones.
