Okay, here's some questions for all of you. Please answer honestly.
1) If you found out your boyfriend/girlfriend had AIDS, would you still marry him/her?
2) If you did marry him/her, would you have relations with them? (assuming no sex before marriage, for the sake of argument)
3) If you did marry him/her and have relations with them, would you have children with him/her? (maternal-to-child chances of contracting AIDS = 35%, not sure about paternal-to-child) 
 1.)  The marriage would be rough and a true test of our love for each other, but yes, I would marry someone given that scenario and also given the fact that I would marry someone in the first place.  My feelings toward marriage are needlessly complex and rather negative.  I am also a stubborn bastard so I doubt I will change my mind towards this matter.
2.)  Er... by "relations" and "assuming no sex before marriage," I am assuming you mean "sexual relations."  If I was already HIV-positive or suffering from AIDs, of course.  Otherwise, I do not think it would be a wise idea.  Kissing is mostly harmless, but it would still arrouse a feeling of uneasiness within me.
3.)  I will not procreate.  I have decided that long ago.
