I am a show-er, and frankly would love to trade for a grower on many occasions. I am very self conscious about my size, and I don't appreciate stares or comments. Even with my wife I get grief. I walk into the room, and she may say something like "oh not now" or "why do you always want to?" I'm not erect, and I probably don't want to either, but it's there and there ain't too much I can do about it.
It does feel like I'm deformed sometimes because every other guy in the locker room can just put on his trousers and go on his way. But I have to mess with mine to some extent before heading out in public. That's why I always wear baggy jeans over boxer briefs.
I've had guys say they'd trade with me, but trust me, you don't want to. Maybe if I was, pardon the pun, cocky about it and a show off, but that is completely against my nature.
