My wife and I have had amazing sex throughout our marriage and I the male half has always been the one bringing out her kinky side. I am 39yrs good looking strong alpha male with a very high sexual dominant side . Now my wife is 45yrs very sexy great in bed and absolutely great person to do life with. However, during our initial sexual fantasy exploration, I feel like she was open to finding me a cake/ unicorn to explore with which was always a fantasy of mine. She also admitted to me she was also wanting to explore with another women because she felt she has bi-sexual tendencies/ fantasies but she feels like she too jealous to see me doing anything with another women. So we talked about it from time to time got on dating apps and lifestyle apps looking for a playmate and every time we roll played the idea during sex of me doing it with another women and she being pretending to be the cake would act as if she was the other women, she would huge orgasms and I would get rock hard. Then she would send me porn with 2 girls and one guy or MFM porn and we would do a lot of sexting throughout the day and it was great because I felt like she was always horny which I love and we were always getting kinky every time we had the chance Now that was 2 months ago and from one day to the next she quit everything cold turkey brought up religion again and said this is all sinful. So she stopped looking for a unicorn, stopped roll playing, got off all the apps and site, stopped sending me porn & all together our sex life has dwindled which has me feeling frustrated. I have cheated in the past on her a few times because of my high sexual nature and have admitted it to her a few years ago. But I feel like she gets so turned on by the idea of me doing it with another girl or maybe she lying but feels like it’s just something I have to experience. Now to stay completely honest maybe she wants to explore with a girl but not include me out of jealousy ? Anyway it’s a fantasy but not a reality now. Not sure what is going on with her and why the sudden change with her any advice would be much appreciated. Thanks!
