First, let's rework this question a tish:
That's right, kiddies. I swing both ways. I'M AFTER YOUR PRECIOUS LITTLE VAGINAS. ALL THE TIME. FOREVER.
Aight, enough with the showboating.
Gemini and Cancer ladies tend to be the ones toward whom I gravitate most, but that's not the only reason why I like Maasa. First of all, she's gorgeous. Second, she has a really multi-faceted, complex personality that made her one of my favorite H!P members in the first place. Many people think she'd make great boyfriend material were she a guy. I agree, but I'm glad she's not a guy :P
I dig people with strong personalities, wherever that strength might be. Maasa has lots of strengths. No boredom here! Well, not that I ever COULD be bored with any of the H!P ladies...
