STDs: a question related to GT40FIED's post

Ok.....so this idea is sparked from GT40FIED's post on herpes commercials. (plug: thanks, GT40FIED, for posting some of the most interesting/highly contested and/or debated topics)

What would you do if you met someone who was open/upfront about an STD he/she has/had? Hypothetically speaking, we'll assume you like the person, otherwise the question is moot.

For has, we'll assume a non-curable disease such as HPV, HIV, herpes, etc.

For had, we'll assume a curable disease such as syphillis, gonhorrhea, chlamydia, etc.
