These women yes are desperate but they sought their
friend/cousin's help as they thought this was a suitable
method.
Women who are desperate sometimes come up with bizzarre thoughts
and hang on to them as their desperation grows closer to their
ideal solution.
This does not mean the solution is wrong.
In Ancient Greece men who desired children from some other
healthy dude's gorgoeus wife would approach the dude and say:
"Nick, you have such beautiful children and they look so
healthy and beautiful just like you. Mind if I can borrow your wife
so that I can procreate some just like yours?" And the men would
agree and borrow wives.
Perhaps the ladies' approach wasn't the best.
Personally, I am looking to adopt.
I have such a ***** up love life. Not because I asked some girl
to sleep with their partner though...
