If you believe sex is an integral part of any romantic relationship you're in, then you may be interested in seeing the answers from this Reddit thread where user u/Acrobatic_Month_1563 asked: "What ruins sex life in a marriage?" Here's what people had to say.
1. "Ten thousand little unaddressed disappointments, which drains communication, fosters negative assumptions, breeds coldness, and turns to resentment. The sex obviously becomes not good."
2. "Stress. Kids, work, finances, or any other kind of stress. Kiss your libido goodbye until you figure out how to deal with it."
"This. When both partners have a ton of responsibilities, high-stress jobs, and deal with innumerable demands on their time every day, and you have a highly emotional pre-teen in the house, you lock into survival mode, and everything else becomes secondary.
3. "Not focusing on the intimacy and emotional safety outside the bedroom. The actual act of sex is the shortest part of the sexual process in my case."
4. "A marriage needs work put into it. When you stop working on it and put it on hold, it won't work. You have to explore new things and show love and affection."
5. "Putting a TV in the bedroom. It distracts you from each other, and then when the distraction is over, it is time for sleep. It slowly kills because the reason to not have sex isn't because you aren't attracted to each other, it's because you are too exhausted to perform, which is a valid reason to put it off. After putting it off at an increased frequency, the initiator stops trying to initiate."
6. "Depression."
"This is my first thought. We still had an active sex life throughout our kids' childhood. Grief and depression killed our libido. Mine is coming back, but hers isn't. And I don't function unless I feel wanted."
