Yeah. Sex is perverted and impure only if you experience it in a perverted and impure way.
Men think sexual liberation means they're allowed to wallow in their loveless lust, perversion, urge to "fuck." Women think sexual liberation means giving up their personal integrity and letting themselves literally get fucked by said "sexually liberated" men. The sex is always penetrative. Vaginal penetration. Oral penetration. Anal penetration. Whatever hole the man finds, he must penetrate it. Whatever hole the woman has, she must fill it with a dick. Absolutely disgusting.
True liberation can come only when first of all you defy what your culture and society is coercing on you, and listen to your own desires. True sexual liberation means that a man defies the thought that a fuck must be hard; instead he loves the woman, listens to her feelings, gets half of his pleasure from her pleasure. It means the woman defies the expectation that she will let herself be penetrated; she listens to her body, discovers her desires, does only that which she feels happy doing, with a man she is happy doing it with.
Touching, kissing, sniffing, rubbing, smiling, looking in each other's eyes, feeling no shame, feeling no reason to feel shame, only cherishing each other's body and each other's love. Penetration comes only if you have relaxed so far that your body accepts it without even the slightest discomfort. It is not necessary, not crucial; just a more advanced, deeper way of feeling each other's warmth.
If you're male I recommend learning to relax so much that you can take it in the butt. It's the most comfortable and liberating feeling ever when your body accepts it. In the process of warming up to it you will understand how difficult it is to reach a state where your body accepts penetration; you will understand how a woman feels and how important it is to take your time with slow, soft, gentle sexual experimentation.
