In Nigeria, a man can dump a wife anytime, for any reason.
Muslim Law.

So rapistism is encouraged? Nice.

I don't find this far fetched at all. I think many people have a very sick sense of sex and are so dug into their own idea of "perfect sex" that they would do just about anything to find it, even if the other person had no other partnering qualities. They will also cast aside anyone that doesn't fit their selfish desire to a tee. For them sex is all about taking and nothing about sharing. They disguise it to look like sharing as long as the sex is good. People like this truly think they are the center of the universe and everything is about pleasuring them.

right, some get off on the 'challenge' of it

the intentions arent always manifested with the same activity,,but whether its pretending to love someone who doesnt require marriage just to get them in bed

or marrying someone who does require it

selfishness has no real boundaries,,,,

The OP is from Nigeria.
