Wow...that couldn't be more wrong. Has this person not heard of the Value for value exchange :)

No. Sex is a selfish act, and it is best when it is aquired for pleasure. When a couple says, "I love you," the word "I" is important. It's not "we." And sex is not good for a woman if she sacrifices herself and her organsim to a man who can't sustain her. The woman enjoys it if she also gets something out of it. The man finds that he gets more of it if he makes sure the woman gets something out of it, something of value--particularly pleasure. So there is a lot of thinking in sex. Sex is terrible if it is seen as a sacrifice.
