This is a preview to a film (The Ugly Truth) that came out a few years ago. It deserved the R rating for plenty of sexual innuendoes and references. Don't watch it if you will be offended. I'm using it to demonstrate a point. (And, no, I didn't see the movie, but I will give kudos to Gerard Butler and Kathrine Heigl who definitely achieved the objectives of the film with plenty of humor and wit. I'm assuming there was at least a partially meaningful conclusion and a little bit of truth.)

Some Christians seem eager to deny the sexual nature of our humanity. I presume there are several reasons for this.
For one thing, the current worldview in regard to sexuality can be raunchy and perverse. It doesn't emphasize, mention, or imply the beauty, the purity, or the holiness inherent in making love as it was intended by its Creator. Instead the worldview focuses strictly on the pleasure aspects in specific, intimate, and sometimes disgusting depictions and details with the goal being self-satisfaction at all costs, no matter what's involved, i.e. the ever-increasing discovery of the exploitations of children and young people in the sex-slave trade. Used profusely as a tool of the devil to corrupt even the purest of hearts, sex appeal cannot be underestimated. The media is all about sex appeal, flaunting it in every venue.
Sometimes, because of the prevalent worldview, it's difficult to disassociate the meaning and consequential fulfillment of lovemaking from the gross saturation of sexual power and pleasure.
How this plays out in Christian/CBA fiction for Christian writers who desire to present real and honest depictions of romance and sexual attractions is in requests for major rewrites, eliminations of incidental words, phrases, or scenes, in order not to "offend" those readers who want nothing to do with anything sexually nuanced, or rejection of their work.
Another possibility for the restricted choices in literature for some Christian readers is the component of sexual abstinence. The worldview mocks both the teaching and application of abstinence, but it's a fundamental instruction for most Christian parents and a personal objective for most Christian young people. Hormones and peer pressure - not to mention constant access to and the aforementioned serial saturation in every medium to succumb to sexual activity - contribute to some moral failures in young hearts and bodies.
It should be noted the objective of abstinence is not about suppression of sexual activity for the sake of forbidding pleasure but rather for teaching the huge responsibility involved in the sexual union between a male and female. Abstinence elevates a sexual relationship because of the spiritual element. Engaging in an act of uncommitted sex degrades it to a selfish physical pleasure instead of seeking the enlightened experience of enjoying full satisfaction with the one you truly love. People of all ages often have a rough time applying the critical nature of this decision in the heat of the moment. Abstinence is the sacrificial high road in the sexual arena. It requires dedication to the Lord and certainly requires allegiance to His ways. In literature it's a shallow endeavor to pretend sexual attraction or intentions do not exist.
Some Christians have come out against young people reading romance novels - which is certainly understandable when referencing secular romance - but Christian/CBA romance novels cannot logically be accused of titillation, although some could definitely be criticized for idealizing relationship and providing pretentious portrayals of non-existent sexual attractions and challenges.
We are created males and females, and the sexual components of our natures can be more powerful than some of us care to admit. Ignoring, suppressing, or pretending this part of us is irrelevant does little to expose the awareness of sexuality and strengthen the intelligent and committed spiritual approach to the beauty God hand in mind when He created lovemaking.
Father, in this sin-torn world we need greater awareness of the beauty in all things you have given us. I was desperate for you in my youth but didn't yet know you in your fullness. I'm just as desperate for you now with this love relationship you offer to all who seek you. Thank you for saving me from the enemy of my soul and his eternal damnation. Your love, O Lord, reaches to the heavens . . . And I wish all would seek your Truth and Life and Way, Jesus. In the Name of Jesus, Amen.
