Sorry to hear that and sadly I was right there with you in my 1st marriage.
We had little to no sex and when we did, it wasn’t good, for either of us.
Beyond that, masturbating was “wrong” to my 1st wife.
I may have said this somewhere on here before, but it’s applicable now for this comment too.
She and I were married in 1989 and sometime around late 2001 or early 2002 my 1st wife asked me if I ever masturbated.
Yes, we were both in our mid 30’s, with 3 children, having been married over a decade and my 1st wife thought I’d never masturbated.
She asked me if I had and I told her yes. She was disgusted with me. I can’t remember if she told me I was these things or if masturbating were these things. Either way, it wasn’t good. She said I/it was “gross, wrong, disgusting and not normal”.
She then left in a huff to go upstairs to bed as this was later in the evening and the kids had long been asleep upstairs.
So I definitely hid the fact I masturbated from my 1st wife.
I didn’t know back then that she’d been cheating on me or that our 1st child (we have 3 children together) wasn’t my bio child.
So to her, masturbating was wrong, bad, gross etc. but her having sex with other men was OK.
And it was OK for her to become pregnant and have a child from another man with me not knowing.
That was fine for her. But me masturbating was a bridge too far for her you see.
