i like to think that garen's first time is with darius. like yeah garen's a handsome guy he could get all the ass he wants but also, there's no way demacia accepts homos at least not to the extent noxus most definitely does. hell he might have even thought he just wasn't interested in anyone period, until the day he saw darius peeling off his armor, and then bodysuit, and saw his rugged, scarred, and sweaty body for the first time.
