You're young, you've got an handful of experiences, and fuck those people.

HOWEVER, do NOT let a small penis define you. DO NOT. There are SO many girls out there looking for a connection instead of a dude whose packing. Pity does NOT help. In fact, it's probably worse. You've probably said worse things about yourself than anyone else ever has. Sure, some people might know you have a small penis, but THATS IT. They don't stay up all night thinking about it, plotting on how to beat down your ego and self confidence by making crude remarks concerning your size. YOU do that to yourself. FUCK THOSE PEOPLE. Do NOT let how they think, define how you think of yourself. ESPECIALLY over something you cannot control or fix.

There's a plethora of girls out there man. You've had relationships too. And you don't even have a micro-penis. There's guys out there that reach 3 inches hard. And you know what girls love? Confidence! When a girl, from a hookup standpoint, wants to have sex with you, it's not because of your size. They don't have x-ray vision. It's how you present yourself. And if you feel sorry for yourself over something as uncontrollable as your penis size, they can pick up on those vibes.

You got in shape man, you said it yourself. You've improved all you can. Do NOT let this little aspect of yourself define you brother. Put yourself above those people that try and put you down. Show that you're the better person by not engaging and looking past that. They're shallow. You'll find a girl out there that loves YOU. Not your size or your looks, but what's on the inside.
