I'm really curious because I have seen this question of mis-matched sex drives from both men and women, and there simply does not seem to be a answer that works for both parties aside from "break up/divorce and find someone else."
Should the one who "only" wants sex 3 times a week just shut up and put out 3 times a day even though they hate it? I see this ending with anger, resentment, and a breakup just as quickly as it would if the party with the higher drive can't accept less frequent sex. Also, really good sex takes time. I mean, 5-10 minute sex has it's place (like when you are afraid the baby will wake back up any second or your lunch break is almost over), but foreplay and consummation that engages both mind and body is not achieved that quickly, at least for women. Who has time for that 3 times a day? Does it simply come down to what one values in a sexual relationship, and if it's not present you must break up or divorce? But what if you truly, deeply love your partner? Can that ever overcome the difference in sex drive?
And why doesn't Prudie ever suggest that these people see a sex therapist? There may be underlying physical or psychological issues that need to be dealt with.
