I actively encourage it and play about 40% of my characters as female, including my newest character (for a total of 1/2 of my current characters being female; 1/3 if her animal companion counts as a character). Sadly, I've never played a homosexual character, I always mean to but then kinda forget about it. I have played a few female rogue spy types that were willing to be with another female if it lead to getting info or an opportunity to steal something, etc... but none were outright bisexual.
I generally have a slight edge for females as rogues/bards; melee brawlers have been a strong edge for male characters; wizard/sorcerer types have been more often male; clerics are evenly split; and druids get their own category.
Possibly Definitely TMI:
[sblock]I've now started playing my third druid. All have been female so far. I'm willing to make a male druid, it's just...I like my druids to be sexually kinky. Like...abnormally so -- dendrophilia/phytophilia; nearly all enjoy bondage and get a thrill using entangle/kelpstrand/etc...; none have been into bestiality yet, but find drawing lines between humans and the other animals silly when they can become animals and often times relate mroe to them than other humans... Ultimately, the large majority of paraphelia cases involve males, so I guess I just like playing against type.
And between the prevalence of bondage spells, wildshaping, thousand faces, eventual physical agelessness, and generic hippie "free love" vibes, I can't help but think of druids as kinky sex fiends.[/sblock]
Oh...my previous female druid flirted with, dated, and got engaged to a male PC played by another guy, for whatever that counts. Left the game before they could tie the knot, sadly.
