No? There's a power imbalance between men and women, yes, but you can't go around charging children for exploring their sexuality consensually. Teach men and women about consent and safe sex, and hopefully discourage it until they're more mature, but making literal, legal children criminals? That's an extreme. Yes, girls can feel pressured into sex, which is why the whole consent dialogue needs to become really embedded in any sexual situation, but teens *are going to have sex.* It's going to happen. And while boys may exert more pressure than girls in general, that doesn't mean there aren't girls that push boys to sex, or girls that push girls to sex, or boys that push boys to sex, whether they're actually the ones they're having the sex with or not.
Additionally, a boy pressured into sex by an older woman is not analogous to a consensual relationship - that's still an abuse of power, and a grown adult should know better. That's the idea behind the adult/child divide, besides the squick of pedophilia. An adult should be informed enough and mature enough to make the decision, but an underage person is not; this is supposed to protect our *vulnerable youth.*
Again, I believe girls have the short end of the stick here, often, but criminalizing teen sex is nuts. Teen rape is already illegal.
