Women are fucking hot.
Men are fucking hot.
I'd do either - both, one on one or at the same time (and have).
The human body has a nearly infinite way of inducing pleasure of being pleasured, regardless of whether or not it's male or female or a combination of both. We need to get over our puritanical fears of sexuality in general. I guess I've never understood homophobia because I find it incredibly self righteous and ignorant. Sexuality does not define a person and sexuality shouldn't be so contentious. I HATE homophobes. Ignorant fucks.
That being said, I have a difficult time understanding monosexuality. What's the point if you don't explore all of your options? But hey - to each their own. Don't fuck with people for who they're fucking.
