You don't necessarily need to look for other positive guys. Many HIV+s date negs. I am HIV+ and my bf is neg. He knows I'm +, he's completely fine with that and we love each other!
If you want to date someone he will love you and accept you regardless of anything. What I'm telling you is this: don't freak out about that... It's not because you are now HIV+ that all your sex or relationship possibilities have become limited to other HIV+s. Allow yourself to try and date anyone like you have probably always done and if someone shows any problem on dating you because of that, well... I tell you what: great! Because you will know he's not the right guy for you.
