Im kinda self conscience about my chest, im not totally flat chested.?!

Don't worry about it, speaking as a Y chromosome carrier you'd be surprised how many guys actually prefer the smaller sizes, also if a guy only likes you for your body well then its not a good habit to get into for later on in life lol, try to pay attention to the guys around you and try to pick one out that likes you for the beauty inside not just the outside. Granted some of these guys may not be captains of the football in terms of good looks but it'll lead to greater happiness ;)

Tons of dating expirience

Dont worry about it. It is what it is, and it will be what it will be. There is nothing you can do but not worry. Relax and enjoy you being you.
