Although some teenage boys will crack jokes about this sort of thing, there's a reason we dont allow teenage boys to make these types of decisions. Their brains are not fully developed, and they cant grasp the fallout of *pimping yourself out to an adult in a position of power in exchange for extra tuition money*. It's the same reason we dont give bottles of whiskey and sports cars to 17 year olds - it'll permanently warp their mind, usually in irreversible ways. Assuming it doesnt ruin their life more immediately.
