Some other promises of birth control have also not been realized. "Sexual freedom" is not a reality because the physical bonding ties us to our "partners" and the more partners we have, the less satisfying the "bond" experience. Freedom should not limit bonds and trust. Artificial BC can do both. Not to mention the fact that women still must deal with unplanned pregnancies even if using the pill. It's a hard truth to face, but here is another one:
NFP never seems to get noticed. A scientifically based method of spacing/preventing births is ignored or seen as backward church talk. People don't think about the lack of side effects, free cost and life benefits received by practicing self-control. Even so, some sex-therapists recommend periodic abstinence as a way of rekindling romance. If it's available every day - no big deal. If some random days are picked to abstain the waiting builds anticipation (and maybe romance) and anticipation leads to greater satisfaction. If only that could be combined with a natural way of postponing pregnancy.....oh wait, that is exactly what NFP does? Amazing!
