Not rejected. Just insisting scripture be kept in context, and people aren't claiming it's saying what it isn't.

1 Cor. 7:6 But I speak this by permission, and not of commandment.
7 For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
8 I say therefore to the unmarried and widows, it is good for them if they abide even as I.
9 But if they cannot contain, let them marry: for it is better to marry than to burn.
28 But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you.
29 But this I say, brethren, the time is short: it remaineth, that both they that have wives be as though they had none;
30 And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not;
31 And they that use this world, as not abusing it: for the fashion of this world passeth away.
32 But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord:
33 But he that is married careth for the things that are of the world, how he may please his wife.
Is there any suggestion, whatsoever, that a man can force his wife to have sex with him?
Keep looking, boys, you won't find it in God's word.
