The version of porn that I consider to be healthy and beautiful, is amateur porn done by real-life lovers who just film their natural sex, in all its intimacy and beauty and sometimes awkward silliness. That actually depicts real sex and real relationships, in a very beautiful, touching way. It's not very common, but on Pornhub the best examples I've found are Wolfradish, Kate Marley, Lindsay & Mike Love, GoodVibesCouple etc. Their videos are typically ones they took primarily for their own memories and pleasure, so they don't forget any intimate moments, and then they decided to start uploading this to Pornhub to share with the world. Less about a fantasy, more about real love and real sex. Beautiful.
But I will admit, I don't touch myself when watching that porn, I actually just watch it, and my body generates internal "womb clench" orgasms due to empathy. I don't actually get that kind of arousal from typical porn, it's interesting.
