You've always had this one friend, Joseph, who loves physical touch. You know he's gay, but you've never known that he likes you as much as he does. Whenever he's with you, he's touching you in some way. Today, for example, you're sitting with your friends during lunch, and he's sitting next to you, with his hand on your inner thigh. You've never minded any of the touching, but since you're straight, you never thought of it as anything other than just skin contact, so you never brought it up
