There is so much that is misunderstood about becoming a cuckold. Many husbands and boyfriends have a fantasy about their women having sex with another man - one who is more endowed, more masculine, and more assertive. But there is much more to cuckolding when it crosses from fantasy to reality.
Here is what you need to consider:
Sex between me and your wife is a very intimate act. If you think you can remove emotions from it, you’re deluding yourself. Your wife will have feelings for me, and I will have feelings for her.
You do not get to control the sex. That is between me and your wife or girlfriend. If we want to kiss (and we do), we will kiss; once you consent to me making love to your wife, it is out of your hands.
She will look at you and your relationship differently after she is with me. She will know and intimacy from another point of view, and she will forever compare you to me (sorry, friend, but you will likely come up short).
Your wife or girlfriend will want to continue to see me. You will be jealous. Are you going to deprive her? She will resent you.
Cuckolding is not only between me and your wife; it is also between me and you. I cannot speak for all in my situation, but I derive great pleasure from dominating you through your wife. I know you do too.
Still want me to have sex with your cute wife? Great. I look forward to a meaningful relationship with you both.
