Not to beat a dead horse, but I read through the first few pages. I totally get where you're coming from hippyherpy. Most sex is casual, which then translate into FWBs situations, and that was that. When you're a good looking dude who can go out and regularly find a willing participant for a night of fun H definitely killed that, haha.
Anyway - I found out for me I have to just be honest. Only way I'm comfortable with it. I've told girls at the bar, and maybe we just go back to their place and cuddle/sleep and might end up sleeping together down the line, or we get back to their place, and it's time to "rumble," and they then disclose that they have HSV-1 themselves, or maybe HPV, etc.,.
It's definitely not like it used to be but you can still go out and have fun. I also realized since I'd always maintained a level of respect/friendship with my "regulars" that many of them were cool with still hooking up, just with condoms.
