“He said it’s her obligation to be the best she can be because men have ‘needs’.”
It’s funny how the Bible has no carve-outs or exemptions to the “no adultery” command because of everybody’s perceived needs. If a man or woman feels the need to commit adultery, they should own up to the fact that they are an adulterer, and quit blaming others for their choice. What if a spouse is injured or disabled and unable to have sexual relations? Do the “needs” of the other spouse mean they are allowed to go off and sleep with other people?
Your scenario shouldn’t apply (for non-loser men who will cheat anyway), because the problem in “withholding” isn’t necessarily the lack of sex itself but rather the rejection.
I know men who haven’t gotten any in 2+ years. Chances are, they COULD have had it at least once or twice, but they stop asking.
There’s nothing quite like the shame of rejection.
The caller was obviously a low life.
