What I write, what I say is my opinion. I didn't write the definitions. There is no ambiguity.
My wife has had sex with other men, a lot of other men. I'm a cuckold, I don't like the term so I call myself a 'hotwife husband' but I fit the definition and therefore I am a cuckold, whether I like the term or not.
To answer your question, if you wife had sex with another person you are a cuckold. You having sex with another women doesn't cancel or even it out.
On another note. Others complain about some being here. IMHO any visitor here for any reason other than demonizing this lifestyle is welcome. If someone doesn't like your post they're free to stop reading and move on.
