When I was a little kid I had a friend with a legit micro-penis that my friends would all make jokes about, and another friend who once showed me his 6yr old boner. I was confused because I had no idea what a boner was, and thought my dick was supposed to be big and hard all the time. So I ended up thinking I also had a micropenis in comparison.
I ended up getting a mental complex thinking that I had a tiny dick that people would laugh at if they ever saw it. I was miserable and depressed and avoided all kinds of normal teenage shenanigans like parties and such because I was terrified that if I drank or smoked weed I would lose control and take my pants off and everyone would laugh. Of course I stayed a virgin the whole time as well.
I got tired of being a virgin when I was 23, and finally said yes to a girl who wanted to fuck me. But I made sure to warn her ahead of time, "I'm small, please dont laugh", and she reassured me, but when I got naked she looked at my dick really confused and gave me a weird 'wtf' look, but she didn't laugh and we fucked and it was ok.. but then afterward she said "you're not small", but I just thought she was being nice.
After finally losing my virginity I felt more confident and started having sex more often every chance I got. But I would still always tell them, "I'm small, please don't laugh", and they kept giving me the same weird looks.
Finally I hooked up with a girl who replied "oh good! I prefer small guys because big ones hurt too much", and after I took my pants off, she took one look at my dick and burst out laughing. I was really upset at first, then she yelled "YOURE NOT PUTTING THAT THING IN ME! THAT THING IS FUCKING HUGE!"
And that was when I found out I actually have an above average wiener.
After that I started pulling it out of my pants when I got drunk at parties and walking around waving it at people... but this was before third wave feminism so I actually got laid instead of literally raping everyone.
