Ok, you asked me to look around for images related to sexuality. So I see waxed headless male torsos selling deodorant. Do I think that waxed headless torsos of young men are sexy? No, I think they look stupid beyond reason. Also, I see Kim Kardashian a lot. Is she sexy? She is, but not at the level that could justify my seeing her so many times when I wait in line for the groceries.

In other words, I have ideas about what is sexy and I use those ideas to judge what is around me. You are saying that people are powerless and let the marketing essentially invade their brains. Is that what you are saying? Oh are you saying that the brains of adolescents, and only adolescents, are especially vulnerable to marketing? I'd be willing to believe that - similar to driving - but it would require neuro scientific research to determine that their minds are vulnerable at that stage.

Unless we have such proof, why not try the good old peer pressure hypothesis? Having sex is a major milestone, so, quite naturally, there are hype, anxiety, a sense of competition, curiosity, and a host of other things that, acting in concert, result in peer pressure.
