Is it possible to be a cuckold without a regular wife ?

I 'm a Belgium man (so my appologies foor my poor english lol)
1.88m, 75kg, brown hair,, shaved sex
and I 've found a girl who's want to have a "real cuckold life style" with a man, so She want's to to married with a man (like me, why not) and she haves 2 or 3 big bull at her disposition for sex !
I have to confess you that, I was very surprized when she told me that !
I can't be his husband, because I'm married with another wife lol
but, that quetsion and that situation is very exciting for me, but my wife does not want to do that... so my question is simple, is it possible to find a girl who's have some regular bbc boy friend ? and if that girl want's to have a "exterior watching (and more) hubbys" ???
If somebody can answers to me (man or woman) it will be wonderful for me

And of course if someone leave in Belgium and wants to talk to me about that (in french or english) it will be also great

Thanks a lot everybody and one more time, sorry for my poor english
