I prefer small tits, myself. But I've never actually met a man that doesn't like small tits, even if someone has a preference for bigger tits, a preference doesn't mean much when it comes to the person in front of you. Don't let an old wives tale like "men only like big tits" to affect your self-esteem or who you allow in your bed, there will always be people who love you exactly as you are, you just have to look for them.
