What do you think of the middle name "Sexton"?

Coming from a normal high school, I know that this kid will get hell from everyone else. If you really, really like the name, I might, suggest "Saxton" instead. It takes the "sex" element out of it, which is what will be mocked. Of course, even "Saxton" is still pretty close. If I were you, I'd play it safe and pick something else.
