What a contentious topic! I do believe that its roots, are communication and that nasty puritan anti-sex tradition. At least in my marriage.
We didn't start that way. But the minute I tried to encourage a bit of innovative, nothing crazy, just expressed my needs, I was shot down, mocked, and made to feel like a selfish slut. I stopped talking, but didn't stop planning for romantic nights, not frequently, but busy schedules, two often-sick children, required some fancy foot work on my part. He later told a MC that he didn't remember those Friday night dates. They went on for several years with few misses.
As the acting out commenced, (I didn't know about it at the time) his attitude toward me changed dramatically. I could do nothing right. Oh, he'd come home (hours late) and grind against me while I was juggling dinner, homework for two kids and my own papers to grade and plans to write and be pissed that I didn't respond immediately. Then he'd disappear to his "office" for a pornfest. I now was pissed, not because of the porn, I thought he was "working" but because I was left to do all the childcare and everything else. His bedtime was 2-3 AM. Or later. Sex was SO infrequent, and eventually, he couldn't finish, a form of ED, later he couldn't even start as the porn use continued, the strip clubs visits accelerated, and the other relationships started. I begged him to see a doctor, why are we not having a normal sex life? He talked, reluctantly about medications, AD, blood pressure, and mentioned that maybe I would have to be content with no sex life due to medical reasons. Hah. I had no sex life. He was having a party.
Briefly, VERY briefly we had this wonderful interlude. He got a job he ADORED. He thought he was a god. It required a long commute, so, once again, I was the one man band, but he treated me like a queen. Our sex life was wonderful. I felt loved, sexy, beautiful... Then he got fired and things were back to normal.
I pleaded with him. "What is going on? Why aren't we having a normal life? It clearly ISN'T the medication!". His answer, "your body DISGUSTS me!"
Okay. I do have to say that I was 5' 100 lbs and a regular gym goer. But two kids, stretch marks and 45.
So, that doesn't inspire me to jump into bed. But, I'm nota quitter. I continue to try. I succeed once in a blue moon. Mostly I fail. Sexy lingerie modeling results in him asking me to move because I'm blocking the TV. I do manage to trick him into it when he's half asleep once or twice.
But, of course by now he's having a PA with someone. He throw she under the bus, takes up with another OW, and we are back on the SK is ugly, fat, and stupid round of the game. No real HB. When I finally got the truth several years after the end of the PAs, I asked him why he would do that to me. "Because I needed a REAL woman! Not YOU!" When I sobbed that he always had told me I was "amazing" he snarled, "haven't you ever heard of positive reinforcement? I was hoping maybe you'd LEARN something!"
I was STILL willing to give him a chance. Maybe he was a changed person, maybe all that nastiness was just, well, whatever. I tried to initiate in a very romantic place, Hawaii, a dream vacation. He pulled away, "you always pick the WRONG times!" I'm not sure how I got that wrong. Moonlight shining in our stateroom, lovely dinner just before, a few glasses of wine, not too many, dancing, etc. I must REALLY not know what I'm doing..
Our last, and probably final attempt was two years ago. Once again, I booked us into a lovely place, dinner, a show, as we were messing around, he suddenly pulled away in disgust and told me he wasn't into necrophila. I, apparently wasn't writhing like a porn star, although from my angle I was enjoying myself. I'm not about to risk the humiliation again. Would you?
As a previous poster said,I don't care if he likes it or not. It's not the way I wanted my marriage to be, but I surely didn't want to be cheated out of a real sex life for 25 years and that's what I got. I think he owes it to me to live by my rules for a change, I was forced to live by his, given an std and had my entire marriage prove to be a sham. I've earned the right to protect myself as long as and in whatever way I need.
