Does the Bible, or any well-known Christian authors, have anything to
say about the problem of sexual incompatibility which was unexpected
because the couple did not sleep together before getting married?
As you probably know, pre-marital sex is a sin according to the bible - but it does address matters of incompatibility, compatibility, and a balanced win/win approach. See below:
1 Corinthians 13:5 In other words, does not over-emphasize self-needs (sexually)
5 It is not conceited (arrogant and inflated with pride); it is not
rude (unmannerly) and does not act unbecomingly. Love (God’s love in
us) does not insist on its own rights or its own way, for it is not
self-seeking; it is not touchy or fretful or resentful; it takes no
account of the evil done to it [it pays no attention to a suffered
1 Corinthians 7:5 Should consider needs of mate:
5 Do not refuse and deprive and defraud each other [of your due
marital rights], except perhaps by mutual consent for a time, so that
you may devote yourselves unhindered to prayer. But afterwards resume
marital relations, lest Satan tempt you [to sin] through your lack of
restraint of sexual desire.
1 Corinthians 7:28 Compatibility troubles (and more!) are to be expected.
28 But if you do marry, you do not sin [in doing so], and if a virgin
marries, she does not sin [in doing so]. Yet those who marry will have
physical and earthly troubles, and I would like to spare you that.
