*Do you mind expanding on what you mean by losing sexual attraction?
Do you not fancy him at all? Like, when you look at him, do you not see anything you find attractive? Not the curve of his mouth, or the line of his neck, or muscles in his arm, or anything?*
The vast majority of the time I look at him and think objectively that he is attractive/good looking. But it doesn't translate into wanting contact or sex.
Very very occasionally I feel a bit of attraction.
It's sort of like seeing him anew/from a distance for a chance, instead of this person who's so incredibly familiar he's like a sibling or something.
He occasionally tries to be affectionate, I'll be honest and say I don't. I respond in s limited way if he does, but I don't have any urge to be affectionate and an not.
Sex wise, not only have we fallen into this platonic - rare (now no) sex rut but I've also fallen into the habit - if I have any drive at all - of sorting myself out, usually using porn of some type. It's lazy, easy, fast, no effort, convenient, doesn't require me to do intimate grooming (beyond the basics) etc.
I know that makes me sound exactly that the porn addicted, selfish, disengaged men do many women post on here about to some extent.
Thing is I don't think it's particular to him because it was the same in the other steady relationships I've been in. I was very unassertive, don't climax from penetrative sex, and when they didn't have the apparent skills or motivation to do other things to help me climax I also got sick of having sex that felt one sided - after the initial high attraction, novelty, honeymoon period wore off.
