My wife surprised me

My wife(f35) and I(m39) have been married for almost 18 years. We were both virgins when we married and had little to no sex ed. I have watched a ton of porn and have some distorted views on sex because of that. My wife has never watched porn or even masturbated.

When we first married I asked what she was willing to try and she said she didn't even know there were things to try. In the first week we had traditional vaginal, oral both giving and receiving for each of us, and anal. My wife hated anal and said she would never do it again.

Fast forward a year and she is pregnant with our first kid and she allowed me to have anal with her. Her ass is amazing and I was hooked, but she still was not into it. A couple of years later same thing pregnant and allowed me to have anal with her. This time she straight up asked if I was gay. I said no but I do enjoy your ass.

Then no anal again until she is pregnant with child 3 and 4. Atleast those times she didn't ask if I was gay. About 2 years after my 4th child was born I told my wife I had been looking at porn and been masterbating our entire marriage and she was not happy. She felt like it was a betrayal and the equivalent of cheating. It was no secret she didn't want me looking at port before this so I was not surprised by her initial reaction, but I was not prepared for what happened next.

Since she was so self conscious about what I had seen she tried to have enough sex to keep me from looking at porn. Man I was in heaven we were having morning sex, lunch time sex, sex as soon as I got home from work and then sex before we fell asleep everyday.

Well one night as we were spooning and I was fondling her breasts I was pushing my disk against her ass. I loved the feeling of her clinching her asshole down and squeezing just the very tip of my dick. Well I was playing with her nipples and with my other hand I was rubbing her crotch with my rock hard dick pushed against her asshole. She had made it clear over the years that I was not having anal with her again so I was just hoping something would change and it did. She started pushing her hips back into me as she was getting into my finger rubbing her clit. Then she really pushed back and let me onto her ass.

At first I was afraid she was going to be mad because I know she hates anal, but she kept working her ass on my dick and my finger on her clip until she was having an orgasm with me balls deep in her ass. It was more than I could handle and I orgasmed in her ass. After we cooled down and were cuddling I asked if she enjoyed having anal. She said no but she knew I liked it so she did it for me. When I asked if that was a one time thing she said she would be willing to do it more often.

Over the next 9 months we kept having sex multiple times a day and she would always have a great orgasm while I was deep in her ass. So I assumed that meant she was enjoying it so I just kept doing it, probably 95% of our sex included anal. I had worked for years to get it 5 times before this then suddenly we were almost an anal only couple.

I pushed boundaries and found out just how willing she was for ass play, she let me eat her ass once but hated it, and she was not okay with anything to do with my ass. Then after about a year of all the anal I could want she said she was done with anal and we are never going to do it again. I was confused because the fastest way to make her orgasm was to put my dick or finger in her ass.

She said she had just hoped that if she let me do it I would get enough of it and then we could go back to normal, but that didn't work so she was done. When I asked about the orgasms she said they were real but she hated that I had trained her body to react to anal the way it did.

Around this time I finally accepted that I was Bisexual and she said she had known for years. I asked if it was just the anal sex and she said no there were other things that made her question. She was just glad I finally accepted what she had known for years, and she insists to this day that we will never have anal again.
