British White Male For Black Loving White Woman

Kind, caring and intelligent white male in his early (pushing mid but we can forget that) 40s looking for a white female partner for a long-term cuckold relationship.
I'm heterosexual but am happy being the beta male in a caring, open and explorative relationship where my partner has one or more black lovers.
A bit of an intellectual in many ways, I would love to be able to share my sexual desires in a deep empathic relationship with a lady whose own sexuality complements my own.
