I should explain. Though watching the reactions is very fun.
I am comfortable ogling, leering, making crude comments towards/about, and generally perving over strangers. People who would not know I'm doing these things to them, and would not be creeped out by it. I am a porn aficionado, particularly when it comes to Japanese porn. I happily peruse the pictures on /r/gonewild and other similar subreddits, and in fact I have a separate Reddit account just for these subreddits. I have a variety of techniques to unobtrusively observe women on trains and buses and sidewalks. I don't take pictures of them, but then again I don't need to, because I know there will be other hot women for me to observe later on.
All that changes when it's someone I know, or at least interact with. I have made it a point never to hit on any of the girls here, and if you go through all my posts in all my accounts, I think you'll find I've kept my word. I also know my behavior can be creepy, which is why I encourage people here to tell me when I'm creeping them out, and I'll knock it off. It's like... once I'm familiar with someone, then I don't want to make them feel uncomfortable, you know?
So, ironically, it's because this thought experiment involves Halforumites that I wouldn't be able to participate. If it was perfect strangers, my name would probably be the first on the list. But when it's people I know... well, I respect you guys too much to have sex with you.
