I have asked guys out before and their first reaction is always really confused. They don't expect a girl to ask them out but it's more "wow this is cool" than "ewww freak!" :) do it, then you'll have an answer from him. Just let him react how he will. You win some and you lose some but it's always worth the risk. Either you get a boyfriend or you can move on and find another guy to like. Hope this helps!
