Most Helpful Guy
I notice a girl when she has a basically nice, friendly demeanor. I notice how she treats other people, and if she seems like a considerate person I notice that as well. I also look for if she seems to have a strong sense of self and her own identity. And definitely also if she has a good sense of humor and doesn't take herself too seriously. Then, since I think girls can be physically attractive in lots of different ways, I'm probably going to be attracted to her unless she's obese or extremely skinny in an unhealthy way. Things like breast size don't matter to me.
