The thought of not wanting to date you because of your breast size is just silly. Like others have said you are more that that, and have such a great personality that I can’t imagine anyone not wanting to be with you.
Strictly speaking on attraction without knowing a woman’s personality, I am definitely mostly attracted to women with larger breasts, “DD and up”, so I would be more inclined to get to know them and go out with them. A woman’s size plays a role in that also because if a woman is 5’1” and has a large C or a small D her breasts will look big for her size and also grab my attention. However Personality counts for a lot and if a woman is warm, fun loving, friendly, honest, ect, and has all those other things that make up a great personality, her breast size becomes less and less important. Conversely if a woman is horrible to be around it doesn’t matter what size her tits are.
Now going back to you Miss L. subtracting your personality, (and that’s a really hard thing to do, because yours is just so fantastic, but for the purpose of answering your question I will.) I still find you incredibly sexy and would want to date you even if I didn’t know how great of a person you were.
BTW, nice bike I like the "tough chick look", (in case you hadn’t noticed.) You work it so well, and I for one like your behind the scenes shots, they show how fun a person you are and make you feel more real, at least to me.
