It's actually illegal at least here in Texas to know you have HIV and not let your partner know. I personally, always wore a condom with DH when we first started messing around & asked him to get checked before we even started having unprotected sex.
I think that's the responsible thing to do.
Yet, I know a lot of people don't start a relationship with someone thinking, "maybe he/she's HIV positive."
If it is a one night stand or just a booty call though, I do believe the responsibility is 50/50.
I think it is both partners responsibility to divulge that information. If you plan to get serious with someone, I think dual testing should occur prior to deciding to go without condoms.
Quoting Iggy Azalea:" I'm watching a show on one of our main TV Channels here in the UK called "The Sex Clinic" that is basically ... [snip!] ... want people to know he should at least insist on wearing a Condom. What do you think? Do you agree with him or not and why?"
by law he should tell its rong what if the other person wanted to know but fealt horrible asking its your place to tell if you have a std
Quoting Ladee+Grant+Lilly:" I mean...I think responsibility lies with both partners. Yes I should ask you if you have anything, or ... [snip!] ... wrap it...but if you KNOW you have something transmittable you should volunteer than information before it ever got that far. "
