I enjoy actually roleplaying the opposite sex more, which in this case of course are male.
Why?...Well I suppose because of all the male influences I had in my life and all my friends for a short while were mostly male. I enjoy being able to play the opposite gender because...well I just enjoy being something that I'm typically not! However, I have played plenty of female characters in roleplays, and enjoyed them just as much, but somehow playing males just struck me always as more fun.
