why would you want to do that and sharing a room with your brother sounds creepy and slimmy to me
There isn't much difference between sleeping naked under a blanket or bedsheets and sleeping naked under your pajamas, right?
What does sharing the room with your brother have to do with it?
lol big deal. do it. don't do it. who cares? what's the worst that can happen?
"why are you naked?" says mom.
"I was hot," says you, or "my pyjamas got all twisted up and I couldn't get to sleep" or "*shrug* no reason"
"why are you naked?" says bro.
"why are you staring?" says you, "why do you care? you gay or something? (not that there's anything wrong with that *snickers*)" or "why not?" *shrugs and gets into bed and ignores bro*
LOL! I can't for the life of me imagine why your parents or your brother seeing you naked presents any kind of issue at all, this isn't the 17th century. if your family's that repressed you're in for a shock when you get out into the world.
Then you probably shouldn't, lol.
