If he's asking if you're seeing other guys, texts a lot, and likes cuddling, it means he likes you for more than sex. If he just wanted sex he would be more distant emotionally. He would also be thinking about other girls and so would not be as concerned about you with other guys and would not text as much. I think the cuddling is the giveaway though - f*ckbuddys don't really do cuddling.
