Is it wrong that I avoid dating flat chested girls?
Is there a reason you don't like flat-chested girls?
My past experiences with flat chested girls have been bad. I feel like my dick is far from their interest.

Why? What's wrong with small tits? I've had bad experiences with flat chested losers.
It's fine that you have a preference for who you date. However, you should avoid bashing others. It's important to remember that everyone is not the right type for another person and you should respect others the way you want to be respected.
