Don't limit yourself to a type. People aren't "types"!
Preferring certain aesthetic traits is perfectly fine, but you might not want to shoo a guy away if he has an ideal personality but doesn't wear glasses. If anyone is really this fogged up by having a type, it can take many learning experiences to change things around.
When you find someone you're really into, you may notice that your preferences begin to change based on your partner. Just because you're attracted to certain people or are into certain types doesn't mean it's truly meant to be. People like who they like.
