I think thia ia most honest post. But ley me tell u my case. When i was 19 i had a penis 4.5 inch erect. I got a gf at that time we had sex she never complained about it. We had an amazing sex that was my first time. I lasted for 3 minutes. And about 5 minutes later i got erevtion again and tjen i lasted for about 45 minutes. We still have sex. N she is my wife now. We watch porn all the time tegether. She sees all kind of penises from 6 to 12 inch.she also crack some jokes about my size sometimea while watching porn. But in reality she love me more than anyone. Nad never complained about my size. May be coz i am the first and last man in his life. I dont know. But i do know now that when she loves u. Size doesnt matter. U will be surprised that she was not screaming like other girls during first time sex. But she had hers tears coming out of her eyes when i was stoking her. So in my opinion size doeasnt matter in case a girl loves u mare than anything. But on the otjer hamd be carefull dont show ur penis to anyome else girl coz she will definwtly laugh at u. Even though she will scream with a 4 inch penis while having sex.
i also have a small penis. it is easier to suck the whole thing when it is small. i like it when a woman sucks my whole penis not just half of it. so dont be ashamed to have a small one.
Your size is just fine for your age and you are not done growing.
No need to worry your developing just as you should be.
