The first thing that often comes to mind is I have honeymooner's nose. It's a medical condition where my nose stuffs up whenever I'm aroused, which is like having the libido equivalent to Pinocchio's nose. All my BF's find out and are all like "wait, so you didn't have a cold all this time" and people go from under-suspecting I like things to over-suspecting I like things.

Despite this, this leads to another thing that comes to mind, being that I'm asexual. I can technically tolerate physical time with a guy if I prepped, but I don't "want" it, look forward to it, or enjoy it. It's just a long ass chore. I do have fetishes... an ice fetish, probably the third thing about me that would surprise any guy I would date. But body to body connection does nothing, hence the asexuality label. If my honeymooner's nose acts up around a guy, it's because they somehow triggered the fetish.
