When we look at someone and they look at us, we usually look away. When we like someone, we just keep looking at them. So, I would say, if he/she doesn't look away very fast it means they are interested in you.
He likes you and he wants to get to know you better.Whether through face to face contact, by phone, email........etc.
To know if your crush likes you when you are alone with her, observe to see if she will make any contact.
The only and best way to know for sure is always asking. Otherwise eye contact and smiling can tell much.
When he has a penis.
You could send someone to ask your crush if he/she likes you. But if you never talk then, try looking at your crush for awhile then see how they glare at you. Watch their actions when he/she is around you. If your crush glares at you weird, that is a sign that he/she likes you, if he acts cool or weird around you, then he likes you. If your crush askes you to call, then he/she likes you. Hope this was helpful. : )
