Excuse me for barging in, but it might be time for more people to intrude into the marital bedroom. Though there are some good Christian books on marital sex, most of them repeat two basic mantras: (1) Christians are not sexually reserved. Behind closed doors we are incredibly frisky and uninhibited, and (2) let your conscience be your guide. If a particular form of sexual expression is acceptable to both spouses, it is okay with God. Let’s not get legalistic in matters where we have freedom of conscience.
I’m not so sure about either of these.
