Opening up my relationship

Over the last two months I’ve had a lot of thoughts and dreams about having sex with someone other than my boyfriend of a year. I’m no cheater and we are so deeply in love and plan on getting married soon. So I’d never cheat on him.

Well, me being me, I’ve gone through his phone a couple times and noticed he’s really into cuckolding porn. I’m definitely an open minded person and have actually thought about that from time to time. I’m starting to feel like opening up the conversation could be a good thing. I have some unfulfilled fantasies, I know it’s something he’s *secretly* into and I feel like it could add that extra heat into our already hot relationship.

Only thing is, how in the heck do I open up such a touchy subject. It could literally make or break us. Do you think it’s worth feeling out or letting the idea die down?
