One of my sons is gay, the other straight. My wife has an idea on how to "fix" the gay one, and I'm not sure what to do.

This is a repost, as my original one didn't get through. Also please forgive me if this is the wrong sub, I wasn't really sure where else to turn. I'm not looking for reinforcement, just need to talk to someone.<br><br>So my wife and I each have a son from a previous relationship. I'll call mine Alexander, and hers Julian. Alexander is 27, Julian is 28. Alexander is gay, which isn't a problem for me or my wife, although her family wasn't too happy about it initially. Julian is straight, and has been with multiple partners in the past. To clarify, my wife and I married about 10 years ago, and married "late", with both Alexander and Julian in their teens. <br><br>Last year we learned that Alexander is positive for HIV. He's fine, and the doctors have told us that with treatment, the virus can be controlled and that he can live a normal life. We were both, of course, in shock, especially since my wife and I had explicitly talked to both boys about safe sex. My wife was more distraught than I was, and eventually told me that she blamed herself for what happened, since she thinks we should have been more insistent to Alexander that he always had safe sex. <br><br>Yesterday my wife had dinner with her family, and afterwards she told me that her sister had suggested that Julian should "show Alexander what a real man is", in order to "make Alexander straight, or at least try". My wife told me that she was considering it, and that she thought it was a good idea since "it's worth a try". I told her that what her sister suggested was both ridiculous and offensive to Alexander, and that it wouldn't "work" even if Alexander agreed (which he won't, since he's in a relationship). I also told her that it was homophobic and that she and her family needed to accept the fact that Alexander won't ever be straight, and it's been that way since he was born. She told me that I wasn't considering that it might work, and that she was going to talk to Julian anyway, because "what if it does work". I told her to not bring it up with our son, and that she was being offensive and cruel. She told me that I was the one who was being offensive, because I didn't want her to try. <br><br>I really don't know what to do. I think that what her sister suggested was disgusting and gross, but my wife seems to really want to try, and I'm worried that she'll go behind my back. Alexander and Julian get along well, but I highly doubt that Julian will be okay with what my wife is suggesting, and I do know that Alexander will not agree. I just don't want this to turn into something worse. Please help me. Also if you could make the post more visible or something, it would be greatly appreciated.
