My boyfriend has recently disclosed to me that he has a cuckold kink.
We've been discussing it lately and I absolutely love how much it turns him on, but I am not comfortable actually engaging in sex with anyone but him. Mainly because I love and only want him, but also because it's just one of those buttons you can't unpush. I don't want a kink to ruin what is a truly amazing relationship. It seems as though he feels the same way about this.
I've thought about roleplaying with strangers online while I'm with him, and he seems to be really into that idea, but what are some other ways I can indulge this kink while still remaining faithful and not crossing any potential boundaries?
