B/c the OP just finished writing several paragraphs about women. Getting laid with men obviously doesn't 'suit' him, so the comment was a bit misdirected.
Generally it's correct, but sounds a bit snarky when directed at someone who is clearly hetero.
Commenter is pointing out something highly relevant about San Francisco, and more importantly the article says, "In short, New York City is more interesting and—I believe—better suited for the startup and a young guy’s lifestyle."
Young guy does not just mean heterosexual. If you're talking about best possible choices for founding a company, for gay men what he's complaining about would not be an issue.
