Being with a sexy woman means other men will try to fuck her. Allowing her freedom to enjoy sex with others can really open up a relationship and make the two of you closer together.
Straight but bi curious. Active, fit; I'm a mountain trail runner. Cuckolding is my biggest fetish; sadly my partner is entirely faithful. In my younger days I experienced some cuckold type relationships, though never a classic cuckold situation, i.e., they were open relations...
