Nobody NEEDS a cuck!
If you are a cuck-minded male and in a relationship already your Woman may choose to keep you on her terms. That's how it works for most
cuckolding lifestyle couples - i'm not talking other types of
wifesharing here.
A real cuckolding
relationship you cannot have with just "any woman" like you suggest in your initial post.
If you are looking for a pseudo-cuck roleplay "relationship" instead, try to contact a professional "Cuckoldress" who is a sex worker in the field of FinDom/FemDom.
...So what do you wish for?
Regards.
