It's not rocket science.

>Priority 1: Can I romance other characters in game?
Male
>Priority 2: Can I dress up my character in cute outfits?
Female

Do neither of these apply? See the following variables:
>Am I role-playing as "myself" or a character?
>If the character has a set personality, what do I feel is more appropriate based on their dialogue and actions?
and perhaps most unfortunately
>Are there meaningful in-game differences to the story or gameplay depending on which gender I pick?

Picking your gender in game has no reflection on your IRL gender identity unless you deliberately want it to.
