Confession about my Cuckold Kinks

I have been married to my wife Anamika for the last 20 years. She is a 39 years old woman- a perfect MILF and gorgeous lady with luscious lips, beautiful curly hair, figure of 38C-32-42, thunder thighs and a sculpted butt to die for. I am also a good looking handsome alpha guy but I have been confused as to why I have so many strong cuck/stag fantasies about her to be lived in real life for the last many years. I have had a strong cuckolding mindset for the last many years however she has not been on the same page due to her reservations on the moral side and the reputation risk involved. However, she has one hell of a wild streak in her when it comes to sex and kinks and she is generally insatiable by me in sexual pleasure. I have tried in the past to convert her and got some limited success due to an internal slut hidden within her which she resists badly to come to the fore.

I am trying to understand this psychological phenomena as it keeps me on the edge. In my normal life I am an aggressive alpha good looking guy who is fit and also well hung and these things generally do not go with popular cuckolding notions on the internet. I have many extreme to normal kinks about my wifey. The kinks involve her with other guys who are much better than me in all the departments including looks, physique and cock size. Main kinks I get excited with are 

She is passionately romancing a guy and cheating on me and she is willingly owned by this guy

She is enjoying flashing, risky dares at the behest of this guy and ready to serve the friends of this guy too even in gangbangs

She enjoying raw sex and getting breeded by multiple guys

I don’t know but when I imagine these scenarios I am able to have passionate sex with her else I do not even get erection with her, 

I have described these cuck fantasies to potential bulls in past – 

1. We go out shopping, dining out, drinking and you behave as her husband and I am with you guys just like a friend- she does lingerie shopping with you suggesting to her which ones to buy while she tries those lingerie. You and she decide everything on the outing as husband and wife and I just follow. I drive as a Chauffeur and you and she sit in the back seat like the couple. We three go to movies and she sits in between and you play with her the way you and she likes. You two just ignore my presence and do everything as a couple. 
   
2. Similar things like above we try on a vacation. Where we three stay in the same room but I sleep on an extra mattress and you two take the bed. 
   
3. You own her in every sense (with her own will). You make her try exhibitionism by making her flash to others as per your will. We are on a beach and you two on the same mattress with you smooching , fondling, feeling,fingering her in public. Take her out for dinners, drinks without panties in short dresses. 
   
4. Some extreme fantasies which I do not know whether we will try in real or not depending on how compelling you are as a Bull to me and to her- such as fucking her raw always, giving her facial with your cum, make her try a gang bang with couple of your friends with she being treated as a sex toy (without hurting her off course) 
   
5. Can try many more depending on your imaginations and suggestions.
