Small dick problems

so I have a small dick, it almost 5.7 to 5.8inch and girth is 5 inch
all my life i have been under confident about it, i am not able to approach any women because of this. I am virgin till now, I had no courage to ask anyone out. I dated a girl literally like 4 years ago. And i am a bit chubby and this body weight makes me feel shit because of this fit gym guys. Due to all these i am very shy to talk to anyone.
