It seems like there is no way to hold a guy's interest unless he has no other options or that he couldn't get anyone better looking...
Most Helpful Guy
Looks are only one aspect of what we go for. Looks are nothing without a good personality to go with it. Most guys have an acceptable range of attractiveness that they prefer. If a guy has a choice between two girls and both have equally good personalities, then the guy will only logically go for the more attractive one. But keep in mind that every guy has different ideas of what is attractive.
The same rule applies for women too. If you had your choice between two different guys who had equally good personalities, you would choose the one who looks like Brad Pitt over the guy who looks like Jonah Hill.
The fact is that both sexes make judgments about looks. Both personality and looks factor in. If a guy has a choice between a hot girl who is an high maintenance, miserable bitch, and a a tomboyish, cute girl who is a lot of fun and makes him feel good, he'll pick the fun cute girls over the hot bitch any day.0
