To the guy who submitted the original piece; Have you ever heard of punctuation? If you are texting to your friends, it's no big deal, but here, you are writing to the world. Capitols, commas, periods and question marks, if you are old enough to get "the talk" you are old enough to be judged by how well you use them.
"The talk"? Yes, I will assume we are talking about the "Birds and the Bees" talk. If your mother is throwing "the talk" in with an offer to buy you new bed clothes, I wonder, "So, what are you wearing now?" If you already have PJs, you probably already have all the other mentioned potential sleep ware; underware, gym shorts, a swim suit and your skin. I would guess what you are wearing now is something that is giving anyone looking you way an "emerging manhood progress report" when you are a little careless. Your mother is probably saying, "No more 'penis peep-a-boo' for you, young man." Before I get to my choice for literal sleep ware, I recognize that your mother is talking about "between getting out of your street clothes and retiring to your bedroom" clothes. All but one of the above options should work in this semi-public realm just fine.
I sleep in the nude and have for decades. I find it to be very comfortable. I'm cooler and sleep better. If the night is warm enough (This is Southern California.), I leave the window and blinds open and sleep on top of the covers. Since my window faces the street, I have noted that the bottom of the window is high enough to block the, "You can get arrested for that!" view from the street. (A very serious factor for anyone who wants to keep themselves cool this way.)
I have more to say, but I have to get to other things now. With any kind of luck, mine will be the next submission.
One writer responded that teens shouldn't sleep nude because they are still developing. If we were talking about a parent who saw other teens swimming, some nude, and told their son that he couldn't join them unless he stripped down naked too, I would agree, but when they are getting into bed alone, they can wear as little as they want, even if it is nothing. No big deal to me.
Some wrote about wet dream stains on clothing vs bed sheets. Between the 2 I would rather have it on clothing, since I wash loads of clothing more often than I strip bed sheets and wash them. But I wouldn't necessarily have him strip his bed just because he created a stain last night. As impressed as he may be with his productivity, he isn't exactly pumping out a quart at a time. It's a small stain. Pull back the covers and it will dry and it won't smell. And this is a temporary problem. A wet dream is a man's body getting rid of excess sperm/seamen. Once he learns "the manly art of masturbation", and has the privacy to practice it once or twice (or more, and sometimes a lot more times) a week, the wet dreams will become a thing of the past.
Still have more to say, but now it's dinner time, so i will get to the last aspect of the responses shortly.
To me, sleeping nude is all about comfort, coolness and rest. It isn't at all about sex. One writer talks about the "raging hormones" of teen boys and says that they are going to get naked before the night is over anyway, so they might as well start out that way. He makes no mention of visitors, so I assume he is talking about masturbating in bed. If I was the boy's father, I would like our home to be a place the boys knew they could have the privacy so they could attend to these needs without having to satisfy them in their beds overnight.
I don't know how old writer Mark is, but he writes about a 13 year old boy's sex fantasy; Some girl will come climbing through the window just knowing he will be naked. And another writer mentions something similar. For someone like me, who thinks like a father of a teen, I'm getting images of pregnant girlfriends a few months later.
Finally, we have another one of those women who write in occasionally and think mom is sex crazed and won't be able to control herself if she sees her son's manly penis. (Let's not forget, mom wasn't writing about this incident. Her son was.) It reminds me of one of the, now greatly discredited, rape defenses. "If you saw what she was wearing, you couldn't blame me!" And incest is kind of a no-no too.
