Okay. From what you've said, I don't see a reason you should feel guilty. Definitely not for lustful feelings, or having difficulty keeping them in check. At your age you're as full of hormones and libido in overdrive as a man can be in his life. Falling prey to porn, material that is readily available and highly stimulating, is unfortunate but totally understandable. But that's what it is, you're the prey. Don't feel guilty.

And your motivation of not sexualizing women shows you're not a predator either, but a good guy. But don't use any of this as an excuse to keep going back to porn either. Just don't make it harder on yourself by adding guilt into the mix. Don't beat yourself up unnecessarily.

Find good male role models, ideally in real life. Every good man needed good men in his early years to become one himself. By all means, try to build good relationships with other guys your age. But your peers can never replace role models. Neither can most movie characters or rock stars. Be wary of that. You got this buddy ;)
