Im 18 ..well almost 19 and ive been having trouble talking to girls face to face.. i have no problem talking to them online or on the phone, i just cant seem to get any further.. i've had girlfreinds in the past and they all noticed that too. i know that to say and how to say it but when i look at the girl i like i turn to mush and just smile like an idiot. what can i do?
