Pyrates!

Life at sea is dangerous for a surgeon, pirates are always looking for someone who has medical knowledge. Unfortunately, your boat has just been cornered by a ship flying a black flag. You're captured, and rumors fly about the captain's romantic past as the ship draws closer and closer to buried treasure...

Not exactly a dating game, but if you play your cards right you can steal a kiss at the end.  There's also gay poetry. Player character is  male.

I'm not really a game dev, I'm just gay and like pirates.
