I'm kinda in the same boat, although I am attracted to both male and female. On some level, I'm pansexual, but I would say bisexual because I like manly men and girly girls. Regardless, I do feel that I more or less fall in love with the person and not their sex or gender. I wouldn't mind being with anybody as long as we are mutually attracted to each other and are truly interested in each other. I get more turned on by intellect, so intelligence plus good looks equals a deadly combo for me. I wouldn't know what to do with myself. Did I digress? I digressed, didn't I? Sorry about that.
As to how you described yourself, I, too, am attracted more toward females than males, but I could see myself being swayed in the male direction given the right mixture of characteristics. I certainly think what you described is bi-curious because you entertain the thought of being with a man, but merely for the act of sex. It's a tough call, but only time will tell.
