Seduce a guy, subtly at school?

Keep having conversations with him. Touch him from time to time on the arm or back. After a longer conversation say I really enjoy being around you and give him a little min-hug. Smell nice, a subtle smell, guys really like that. Wear your skirt just a tad bit shorter and maybe open one more on on your blouse, but don't over do it. You want him to be your boyfriend, not a one night stand.
