I'm actually not surprised that girls are a lot more open with their "attractions" to other females; especially compared to hetero guys.
As women, we focus a lot more on sensuality and let's face it, females are very sensual, sexy, and seductive.
I can look at a girl and say to myself, " Wow, she's so beautiful. Her legs are gorgeous. Her breasts are almost perfect!" She might even turn me on a bit. But at the end of the day, I know I'd rather go for a man.
When I see a really hot guy I feel completely different than I do when I see a hot girl. I might get flustered, feel butterflies in my stomach, or get extremely giddy with a dude, while a pretty girl just makes me look for a really long time and I just admire her beauty like it's a work of art. Do you get what I mean?
A lot of people actually think I'm a lesbian because I've always been able to be open and joke about things guys would, like,
" Dude, look at her tits!!!" and yeah, I've seen a bit of girl/girl porn (which is marketed toward straight men, not lesbians) and it's alright. I've also watched straight porns and gay porns (yup, all dudes. My friends think it's gross but it's actually not that bad) and I think getting turned on by those things just means you are a sexual being, not a homosexual, bisexual, heterosexual, pansexual, or whatever.
I know I'm only 16, but I'm secure with my sexuality and quite open about it. I could write on sexuality for days because it really interests me. When I think or fantasize about a woman, I just know that I'm a normal, functioning person.
I don't believe anyone is 100% gay/straight, anyways!!
(I've got big boobs (32G), too, but I seem to be fascinated by other girls with large boobs. Heh!)
