Post one first, and I might be tempted to oblige.
I don't think anybody here would like to see a guy's face. Yours, on the other hand, some would.
This leverage won't work on me as well because I'm just gonna post a face of some hot guy I find on google and present myself as whoever I please. Your photo would have to correspond, though. And you still wouldn't be even close to tempted to oblige, because you don't care whether I show my photo or not.
Rather I'd ask, why did you have the photo up before and changed it later?
