So I don't know if you saw The Hangover part 2 but in it the guy who plays Chang on community has a scene where you can see his dick and it looks like a tiny button in a ball of hair. They interviewed him and he said he knows it's small but doesn't give a fuck and was happy to flash it to the world. I haven't seen you penis but it's probably bigger than his. Only you can let that shit affect you. And if they see you truly don't give a fuck it will ruin their fun. Just say "your mom said it's the biggest she ever had so...". Also for laughs watching the seinfeld episode where this happens to George. Not all women know about shrinkage!
