I believe there have been tons of ‘trans’ sorority members before and those are also biologically male so I don’t think this is the first or maybe just the first that outright admits to being a male although I don’t think he’s the first there either.
Look, just because you had consistently bad dating experiences in college - with many a "surprise" à la "The Crying Game" - doesn't mean that this is a widespread phenomenon.
