Yeah, but it's not that simple. Like with food, you can fix your own, or you can be served by someone else. In the end both meet the purpose to relieve the hunger. Yet, when someone cooks for you, sets the table and invites you to dine in their company, it's usually a sign of appreciation. It's because they love you and because you deserve their love. Similarly, when you have sex with someone, you need to be worthy and so are they. It's mutual. When someone doesn't have sex it's because something it's not right. And before it is, sex it's very difficult to happen, or is not natural. That's how I feel about it.
