When you bring the fetish into your relationship, many things can happen. In the majority of cases, the reaction will be: "No." Along with "You don't love me anymore?" "You're making up excuses to cheat on me too!" And these things, so it's common to ask, "What can I do to make it work?" Just like you, I went through this. For about 2 years, my fiancée and I had constant conversations about cuckolding. Always bringing it up at opportune moments. The fear of "losing her value as a woman" to society, me not loving her anymore, and so on. During all this time, I focused on finding out why. Seeing what tormented her about it, what could be done, how to do it, her paranoia, suggesting things here and there. After a year of these conversations, she got together with someone (nothing too serious, just kissing), two years and she had her first sexual contact.

The tips I will be giving you are exactly the steps I took. These were the actions that made my fiancée go from a deep aversion to the idea to almost a Hotwife. Keep in mind that you may need to adapt these tips to your reality since you and I are different individuals in different relationships. That said, let's get started.

1. Stop thinking about cuckolding with your cock.

You need to think about it rationally. Separate the fantasy from reality, rationalize. "What do I like about the fantasy? Do I like seeing my wife with another man or am I more imagining a threesome?" Rationalization is important because one of the common contents of Cuckolding are the captions that, for the most part, are fantasies that will not fit into your reality and, if you force them on your wife, you will only be distorting her.

1. Always consider the possibility that this fantasy will NOT be fulfilled.

Contrary to what is spread around and even in some comments on the sub that "Women's biology is for cuckolding" or "Every woman likes to have 3284728472 partners", "all women like big cocks", no, that is total bullshit. Your wife may simply not like the fetish, not be compatible, etc.

1. Cuckolding is for YOUR wife to seek pleasure.

I know it seems like I'm being obvious here, but the amount of cucks on this subreddit who seem absorbed solely in their fetish and own pleasure, makes me consider this an important point. Cuckolding is based on the idea that you are giving your wife the freedom to satisfy herself sexually. Does she want to have sex with a man, a woman, with two, three, do this and that? Okay, it's HER sexual desire, talk about it and when you think you're ready for it, go for it. If you are somehow forcing her to fulfill such a fantasy, then the whole premise of "Sexual Freedom" goes out the window and, due to a potentially bad experience, your wife may end up being 100% against it.

1. Take it slow.

Don't just show your wife a caption and say, "I like this shit!" (Trust me, that's a terrible way to do that.) Start slowly, and bring up the conversation in a calm moment, maybe after sex if you prefer. Introduce her to the fantasy calmly, and avoid introducing communities too early in the conversation (many things are good, I know are extreme cases, but that can turn new people off). Talk about her concerns about the subject, reassure her about her fears, to calm her insecurities. Support her, WITHOUT putting any kind of pressure. Let her take her time because the fantasy is for and about her pleasure.

1. Limits.

I know, you must have seen a lot of posts here (or captions about it) about limits that were broken for some reason. And that's okay! If you and your partner are okay with ending them, it's the best decision to make!

However, limits serve both to reassure you (since I know that many cucks and even wives/GFs/Fiancees, like mine, suffer from an "epiphany" when they cum and they feel terrible) and to reassure YOUR wife. (at least mine felt very reassured).

Rules are the most fragile part of cuckolding because it can happen that you just let go of them and everything is fine, but I strongly believe that they are important for the first time, just for the reassuring reason.

1. Talking.

And here I will be captain obviously but, come on. You have already realized throughout the post how important talking is. It is the most important thing not only in fetishes but in the relationship as a whole. You can NEVER ignore the conversation, for any reason whatsoever. The conversation is the pillar, if you do not focus SPECIFICALLY on what is causing the problem, you will not solve the problem.

Did your wife come to you with some problem related to cuckolding (or any other fetish)? Sit down and talk about it. Find out why, what the problem is, the reason. Etc. (For example, recently my wife told me that she did not understand the appeal of flat cages, so we sat down and discussed, for quite some time, why. By explaining it in detail, everything worked out.)

Also: Aftercare is extremely important for you AND your wife. After the sessions, have a period of lovemaking, relaxation, and lots of cuddling.

And that's all. I hope it can somehow help you bring this into your relationship. Good luck to yall
