Is she Irish? Sub optimal attitude IMHO. Not trying to be negative but I find many of her comments reveal a disappointing disposition. Catholic guilt trip and quite self centered. The aversion to being touched by anybody else is not a sanguine sign.
You've given her the family life she wants but shes reticent to give you the bit of kink you desire. In the west that's the norm, the culture of sacrifice by the husband to maintain marital bliss , but in other countries it is not so. Im no machista nor misogynist, I love women and treat them like princesses, but pleasure and preferences are too important to subordinate.
And you are only in your early 40s, so those urges will just get stronger I assure you. And her body will . . . .not get better. So unless her attitude improves I think you gotta get a mistress who is more willing to satisfy your desires rather than selfishly focusing solely on herself.
A decade ago went to sexy Halloween party with Colombian MILF ex. Horny as all get out, loved doing it in public . She did tell me "im not into swapping". So at the party it started slow. Finally things started heating up and two girls were going at it as a crowd gathered around them. I tried to pull her in closer excited at this progress. She pulled back when she saw what was happening nd said lets go.
My interest in her vitiated in a nanosecond and I asked her to move out not too much after that epiphany that she was not the one.
