Everybody has feminine qualities and masculine qualities, and that applies in real life, too.

Aeris is probably very feminine. Tifa is borderline. The way Yuffie talks, I feel like it's a teenage girl, but I feel like if any girl is masculine in FFVII, it's Yuffie.

Cait Sith is probably the only male character that is kinda feminine.

I won't make this post that long, b/c I'm responding to a sub-topic.
