There are, once in a blue moon, women out there who are looking for a man to cuckold. We know one cuckoldress whose husband passed away. I've met a couple of women on FetLife who are dominant and like submissive men, but also make it clear they have no intention of being monogamous. But women like that are very few and far between.
I agree with most people here. Wanting to be a cuckold is not commonly enough to build a stable and lasting relationship. First of all, if you are a cuckold right from the get go, it's hard for me to see where you'd get any sense of security and stability. For most people (I'm sure there are exceptions), I think jumping right into one-sided promiscuity can be a difficult thing, if you didn't start out by making sure you and your life partner always put your relationship first. Personally, if I'd started watching my wife get fucked far better than I have ever fucked her, before I knew for sure that she wasn't going anywhere, I think it would be very difficult for me to show the kind of support she needs and deserves, or the kind of confidence and security she's attracted to. I think it's likely I would have feared her leaving me, and senselessly fucked things up. Instead, we took the time to build an extremely loving and mutually rewarding relationship, and cuckoldry gradually became a part of it 15 years after the relationship started. We support each other through thick and thin, I know my well-being is important to her, and she knows I'm secure in our relationship and can handle the complex, potent cocktail of emotions that bubbles up in me when she cuckolds me, so she feels free to play and be creative and adventurous and devious. I'm not sure I would even recommend cuckoldry to people who don't have that strong foundation to start with. My fantasies can be pretty strong and intoxicating, but we gradually explore most of them together as a couple. No one of them is worth risking the happiness our marriage brings us.
I look at it this way. Who's happier: the guy who is in a stable, loving marriage with a committed life partner, who has a kindred travel companion, perhaps a mom for his children, who is unlikely to die sad and alone, who can communicate fantasies openly to his partner without fear of rejection, but might not get to explore every one of them if she doesn't share ALL of the same desires; or the man who might get to explore his fantasies with someone he may never connect with that deeply, and likely has a few relationships that don't last, with long stretches in between because he only goes for women who are primarily physically attracted to men his polar opposite? To each his own, and more power to you if you decide the latter better describes you. I'll take the former 10 times out of 10. I'm proud to be my wife's cuck and beyond grateful to have a partner willing to explore these murky waters with me. But I'd be a damn fool to be more driven by my mental porn than my lasting commitment to her. If she decided tomorrow that she never wanted to fuck another black guy or even that she wanted to give monogamy a go, I'd absolutely validate her feelings, do whatever she needs to do, acknowledge that or journey is constantly evolving, and continue to communicate so we can keep finding the right balance, giving each other as much of the other needs as we can do, while voicing our own needs and prioritizing our well-being.
