Google produces several contradictory websites with strong opinions about what kinds of sex Gileadites should be having.
The general consensus is that you shouldn't have sex until your (monogamous, heterosexual) marriage and then shouldn't get divorced afterward; that you shouldn't use pornography; that women should dress modestly (it doesn't seem to occur to anyone that someone might be visually attracted to men); and that husbands and wives should have sex with each other regularly.
Subjects of debate include:
-We know it's okay to masturbate to collect sperm for artificial insemination. Is it okay to masturbate any other times? What if you and your spouse are in different states, or your spouse is too sick to have sex? What if it's treatment for sexual dysfunction? What if you fantasize about your spouse? About your future spouse? What if you don't fantasize and just concentrate on how nice it feels? What if you don't fantasize and concentrate on thanking God for the gift of sex?
-Are romance novels and romantic movies technically pornography for women because women aren't attracted to men visually and are instead interested in men's personalities and romantic devotion?
-What exactly is immodest dress? Positions range from "if you cover from the neck to the knees you're fine" to "wearing a V-neck sweater is a sin because it will make men think about the possibility that you could be wearing it without a shirt."
-If you fall in love with someone before you get married, is this permanently giving away a piece of your heart and thus robbing your spouse of something that they have a right to expect?
-Given that of course people are supposed to not lust at all, how much not-lusting can be reasonably expected? Should men 'guard their eyes' by making sure not to look at women's bodies or have extended conversations with attractive women or read informative books about sex?
-How much should people know about sex before engagement? Positions range from "a comprehensive accurate sex education" to "nothing except that sex is a good thing which God intended for marriage and they definitely shouldn't have it before, any more specifics like 'what exactly is sex' will just encourage hanky-panky."
-How far should people go before the wedding day? Positions range from "no kissing until marriage" to "no touching genitals until marriage".
-How should people form relationships? Some people seem to go on dates with people they like, fall in love with them, and get married. Others seem to think that if you find someone you like, you should pray to find out if God wants you to marry them, and if so the man should ask permission from the woman's parents and then they should discern whether they want to get married in a committed fashion.
-What exactly is cheating? If a woman flirts with someone or falls in love with someone else or has a male friend, is this cheating? If a man thinks another woman is sexually attractive or fantasizes about sex with her, is this cheating?
-Is it okay to refuse your partner sex? One side holds that if a woman's husband wants sex she should say 'yes' as long as there's no medical reason to refuse, because she has to understand that sex is the only way that men feel loved, and you're just setting him up to lust and/or cheat on you. Another side holds that husbands should be understanding of women not being in the mood, and try to get them in the mood through romance and reducing their stress. (It doesn't seem to have occurred to anyone that women could want sex more than men.)
-What kinds of sex are allowable in marriage? Everyone is in favor of PIV and manual sex, but there is great debate about oral sex, anal sex, stripping, lingerie, sex toys, roleplaying, and BDSM. One position holds that if a man thought of these ideas it's probably because he's watched too much porn and objectifies women, because they wouldn't think of it any other way; one position holds that anything is okay as long as both people involved think it's okay; one position holds that God invented these sex acts and it's a sin to refuse any such act your husband wants. (It doesn't seem to have occurred to anyone that women might want these sex acts too.)
-If pregnancy would be risky to the health of the mother, is it a sin to refrain from sex? What if you just have kinds of sex that can't lead to babies?
-If a woman is fat and/or has short hair and/or doesn't wear nice clothes and makeup, is it kind of her fault if her husband cheats on her because she let herself go? Alternately, is this a sin?
Also, a small yet fervent group of people think that male headship means that a man should be allowed to pull his wife over his knee when she misbehaves and spank her, and then they have sex afterward because of the amount that proper relationship roles arouse everyone involved. Everyone else seems to think this is degrading, misogynistic bullpucky. (Gileadites don't swear.)
