The gender ratio of every character (NPC, Persona User, Non-Persona) is 14 to 10, male to female. Out of the Persona Users, the ratio is 10 to 6. 11 to 9 if you count the inactive characters. Some of the males haven't posted recently, so I guess it just feels like there's more females since the girls tend to post more than the guys. The girls may have options, but they [i]all[/i] know who the best choice is.

Hierophant and Devil are apparently the only ones left to choose from, since Death and Temperance were just taken by some new people IIRC. Don't feel like you have to balance the gender ratio, though. Do whatever's comfortable for you.
