Your enjoyment of a Victoria's Secret magazine or website isn't unusual at all. I doubt that anyone thinks that you're weird ~ don't worry about that!
What surprises you about not being yelled at for going to these sites?? You're young..having pics up of sexy photos is pretty darn common for boys and girls. So long as you don't become too obsessive about it, I'd expect your mom to be pretty understanding. Heck, a lot of men hold onto sexy calendars and posters & display them in the garage for
many years!
