I was in the same position as you although it was me that put a stop to the sex life. I wasn’t attracted to him and, even though I had accepted this was the way my life was to be, the power of feelings/hormones/need to be desired eventually caught up with me and I started looking elsewhere.
Our sex life was awful. Boring and lacked passion. He didn’t do anything other than get on and off (literally, two minutes and done). No kissing, no affection. There wasn’t any affection elsewhere either. No holding hands etc. But, like you two, we got on well but it became very obvious to me that we were nothing more than friends.
I had suspicions my stbx was gay too. He was 36 when we married (I met him at 21, when he was 31). Still lived at home and he didn’t have any history with women and it was obvious he had spent his time with men. All had a mutual hobby. They’d go away together (for said hobby) and he would stay in the same room/same bed as one of them which I always thought odd. I was very naive and inexperienced tbh. Still at university when I met him and hadn’t really had a boyfriend before.
Anyway, stbx always mimicked this man. He would dress like him. Talk like him. Say the same things and do the same facial expressions. I found it odd but I suppose it’s the same as someone picking up an accent in a new area. Nevertheless, I ignored it but had suspicions. Other things that made me think were the fact he never got horny (well, not when l was around) and never looked at other women. He just seemed to lack that sexual drive towards women. He was always very critical of women too (stuff like negativity around women drivers).
I was unhappy and unfulfilled but we had two kids (last one convinced artificially as he we struggled to convince - probably because I was starting to really check out by this point and the fact sex was awful). I didn’t get turned on with him so my passionate side didn’t come out.
Marriage became sexless - for over a decade.
I won’t go into to much detail but, like you, my head was turned and, unlike you, I did cheat. It started off as a friendship (both of us married and both living in sexless marriages). We met online. Chatted on the phone/messenger for a good year. Well, we met and the chemistry between us was electric! On every level. We kissed that night but nothing else however we did have sex a while later - numerous times. Both of us passionate which each other. We talk about it a lot but it is clear he won’t commit to me and he is encouraging me to meet someone else (which is heartbreaking for me). I ended my marriage after meeting him
for the first time as I was suddenly thrown into emotional turmoil. I could not fight these feelings. Of course, I am suffering due to going through a long and expensive divorce. I feel guilty about my stbx as he was a nice man but the chemistry just wasn’t there. I’d forced celibacy on him but also on myself. It clearly wasn’t just sex though, it was affection that wasn’t there too. We just didn’t connect. If we went for a meal, he’d sit in silence.
The other man is still in my life 6 years on. We have become great friends and fancy each other like mad. However, he will not leave her so it has left me alone and struggling. I’m probably more unhappy than what I was before as I am still not getting my needs fulfilled and there is a huge gap in my life.
I have tried online dating and have been treated badly and messed about by a few so I’ve given up.
I actually checked my stbx FB last night and it is clear he is having weekends away with the same man I mentioned earlier. He hasn’t been seen with another woman and I doubt he would be.
One thing I did notice was how many compliments I get from OM and the men I met from online dating. Most very tactile (although I didn’t have sex with any of the online dating ones as it was usually a couple of dates and they (or me) didn’t take it any further. My stbx NEVER complemented me. Ever! He never seemed to notice if I was wearing a nice black negligee. He never noticed other women either.
Sex with the OM was amazing. He was so giving and did things with me I had never done before. I have never been so turned on in my life!!! He kisses me so passionately. I know it is wrong and it should never have happened but it did. I can’t change that but I know now that it all happened because I was missing something.
So, to prevent this happening to you I think you need to have a long, hard think about you marriage and ask if you are happy to live like this forever. Being with the OM made me realise what I was missing. I have no regrets about ending my marriage (of 23 years), I just wish I had had the guts to do it earlier. I didn’t want to hurt him, so I had accepted my life the way it was, but - what I hadn’t realised - I was hurting myself!!
Please move on from this marriage if you continue to feel this way. You will just end up tormenting yourself. How old are you?
