A year ago I had a make out session with a guy and some of his spit came into my mouth and I ended up swallowing it. I ended up ending thing a few weeks later and he went off to college and I went my own way. Now I am hearing from a good friend of his that he has AIDs not HIV but AIDs. I am freaking out because I don't know if he had it the night we had our make out session or if he got it later. I didn't have any cuts or sores in my mouth and I don't think he had any in his. But is it possible because I swallowing some of his spit that I could have it?
