Hope everyone doesn't mind me jumping in, but just wanted to share my experiences from a male perspective and to share my cautionary tale for those on this thread thinking about getting sexual attention outside the marriage or looking for an illicit partner . Apologies for the long rambling post !
Last year myself and my wife had reached the stage were we wasn't even spending any time outside the bedroom together,I was focusing on work and she seemed to have mentally checked out , always busy with others, never any quality time together, zero intimacy, I'm sure lots will agree you can be married and feel lonely .
I then developed initially an online friendship, with a sexual element, someone similar to me, same situation and going though the same things . If you've never gone behind your partners back or cheated I can honestly say it's exhausting, feeling like your living a lie, the deceit, the fear of being caught out, sleepless nights wondering if your a bad person. It's almost like an addiction, the buzz or high when you receive a message or phone call, but when it wears off I just felt terrible. I don't have a particular strong moral compass but nothing prepares you for the feelings of guilt or wrongdoing.
I couldn't bring myself to be intimate with an other person, deep down I knew that was a line I couldn't cross and that's were the problems began. I ceased all contact with my online "friend" . The OW took great delight in finding personal details about me, to use as a lever and weirdly to try to keep me in contact with her.
The upshot was she told my wife, via social media and in the aftermath my wife banished me from our shared home, refused me access and for a period the only possessions I had was my work clothes. I understand what I did was wrong, but my life has honestly been ruined by my actions. There's people I've known for nearly 20 years who no longer speak or acknowledge me.
The OW clearly had rejection issues and I've since learnt her marriage broke down the same week I ceased contact, so I clearly took a lot of flak that perhaps should have directed elsewhere.
No real reason to this post, except if you want to look elsewhere, I recommend you end things properly via separation, rather than look for attention outside the marriage.
