The most thrilling thing? For me, a cuckold of 3 years to a younger Asian FemDom wife, i am white 50's HWP fairly attractive and before her--perfectly straight up hetro love female everything. Now, the most thrilling thing---how she flipped me to adoring black men and desiring to have sex with them while losing desire through physical punishment when attempted with her. I mean, i am totally turned on by the superior black male no matter his age, physical statue or penis size. How i am fully erect and have those butterflies in my tummy when i am kneeling before the black male while she giggles, flaunts it and humiliates me for being a cuck sissy, etc. That is the most thrilling part. Everything else is secondary to that.
