Although the likelihood of getting HIV with todays drugs and using common sense, I don't think I could be able not to think about it, or stress about getting it. So I would say it would be best not to date someone who has HIV, for me that is.
Isn't the sex implied? Otherwise how would you even know or care that the person was HIV+? Isn't that something that comes up when you're throwing around the idea of banging?
If you read through the topic, you will see that there is a stigma to HIV that includes simple things like just sharing a soda at the movies. Holding hands. Folks up in here don't really know what transmits and what does not.
When I am dating someone, I am just trying to get to know them. Then there's an escalation in intimacy. If I'm having sex, we've moved beyond "dating."
