I have a dilemma about my fantasies with my wife([mfm],[mmf], sharing, etc.)

It’s a very long story, so please just read if you are really interested (I think it’s a very interesting one though). We’ve been together for 11 years and married for 5 years. My wife is also the one I had my first (and only) sexual interaction with (same counts for her AFAIK. Proud!). I have always been the one with a higher sex drive, but lately this has changed positively, we’ve kind of lined up. I’m 28, she’s 27, her amazing fit body hasn’t aged a day, even after having two children, so even when pleasuring myself 99% of the times I have always imagine her. We have some homemade stuff as well, but sometimes it’s enough for me to just watch a picture of her, doesn’t even have to be a nude. Until this point I think all of this is alright (right?).
