Boyd K. Packer of the Council of the Twelve, in a video for youth on sex and morality, stated that within the bounds of marriage, sex is an important gift to help reinforce the bonds of marriage. Certainly, most Mormons I know have good sexual relationships within their marriages. I have never been told by any church authority that the sex drive is evil nor has any bishop interview poked into my marital relationships. I do know some mormons who are extreme prudes (do doubt there are prudish evangelicals and catholics as well). I'm sorry for them.

Absolutely not. Sex is good and right for so many reasons, not just as a means to have chilren, but also to help build a loving and intimate relationship between husband and wife. And while that power to procreate IS sacred, sex in the marriage relationship is also about expressing love, having fun together, becoming close, comforting one another and also satisfying your healthy desire for one another. It's the time, the relationship, that can make it wrong to have sex. I think the best scripture on this is found in (the Book of Mormon in) Alma 38: 12 "Bridle your passions, that ye may be filled with love." A bridle doesn't kill a horse; it controls it. Passion is good, if you have control over it. Our sex drives shouldn't rule us, cloud our decisions, make us inconsiderate to our partners. We should have enough control to wait until we are married to have sex, and also to resist the temptation to cheat on our spouse. Again, I think the bridle is an excellent metaphor for passion. We don't seek to control a horse because it is EVIL, but rather because it is so POWERFUL. And what is the reward for us and our relationships if we exercise control over our passions? We will be "filled with love".
