Of course many christians are afraid of it.
they believe it was a product of the fall and God hates it, but allows it ONLY for making babies.
Never heard such a thing ... nobody I know who is christian hates it ;o)
How beautiful and pleasant you are, O loved one, with all your delights! Your stature is like a palm tree, and your breasts are like its clusters. I say I will climb the palm tree and lay hold of its fruit. Oh may your breasts be like clusters of the vine, and the scent of your breath like apples, and your mouth like the best wine. It goes down smoothly for my beloved, gliding over lips and teeth. I am my beloved’s, and his desire is for me.
~ Song of Solomon 7:6-1
The husband should fulfill his wife’s sexual needs, and the wife should fulfill her husband’s needs.
~ 1 Corinthians 7:3
Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.
However, each one of you also must love his wife as he loves himself, and the wife must respect her husband.
~ Ephesians 5:33
Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh.
~ Matthew 19:5
