r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
It's not a question of being single, I'm actually in a relationship. However, the relationship is open and I would love it if I could interact physically with more people, just as a casual thing that happens. When I said telling everyone I met "you're cute want to make out" everyone was a lot closer to accurate than you may think when the average person would say it in that context.
Ah. So you need a more complicated T-shirt!
Incidentally, if you're interested in making out with men who are attracted to your gender, "you're cute want to make out" may indeed be reasonably effective. Although, given that you're asking this question on this forum, I think I can assume you're a heterosexual male, in which case that advice isn't very helpful.
