personally I couldn't care less. If I spy some from a distance or out of the corner of my eye, I admire shape and proportions, but If I choose to hang out with someone I only care about their personality. Though I would be unlikely to be attracted to some one who was down right ugly - sorry, I'm blunt like that.
I agree with Fluffy (damn it, the pictures threw me off) - if it's natural then it's dandy, but if you're not able to get the job done.... well...
But as far as breast size? I think it matters more to the girl than the guy, most guys I know like boobs in general. Girls, I've met some who detested theirs because they were mistaken as boys or, conversely, they ended up nearly giving themselves black eyes every time we drove over a speed bump.
Adventure stories! They can be fantasy, modern, sci-fi, all kinds! Give me some good world travel stories and I'm all over it! I also enjoy romance stories and even though I tend to play females I love playing gay men.
