Claire, thank you. I think you summed up each case succinctly. It's simply a matter of risk/benefit analysis.

I personally think herpes or risking AIDS is a price worth paying if it avoids the risk of wasting my entire life with a woman I'm not a good match with. I mean, what's the difference between dying from AIDS or never have been alive? Naturally I'm not in a position to judge whether abortion is worth it or not.
