Answering a lot of posts in a jumble here:
I think it's very valid to raise the point that you're only hearing my side of things. Although I'm trying to be as objective as possible, obviously my account is going to be biased towards putting myself in a good light. There's nothing I'd change for veracity, although there are details I've missed out - mostly because DW would be utterly mortified to know that I posted them. She would be to know that I'd posted this much but although she'll probably never see it, it feels disloyal to take it too far.
The decline started years ago, when the physical side wasn't awkward but wasn't completely fulfilling for DW (we were both in our early 20s, but kind of young). In trying to make it better we just made it awkward and self-conscious and a lot of spontaneity and fun went out of it. That became the norm and eventually it stopped. Since then I feel as if I've been on the back foot and responding to her, because any attempt by me to change things is seen as pressuring.
I'm pretty sure that I haven't interpreted affectionate non-sexual contact as a green-light, but she might differ on that. Presumably we'll discuss that at counselling - I'm very glad that she's finally agreed to get counselling.
I wouldn't want sex out of a sense of duty from her. That'd just be sad and depressing and I'd feel like a rapist. No offence to people for whom this works.
I've put on a few pounds (haven't we all by 39
?) but I look OK. I asked her the other day and she said I was 'above average' looking. I don't think I'd be starved of female attention if I was looking, not on grounds of being hideous anyway. Good personal hygiene, dress OK etc. Own teeth and hair. Generally come across as confident and cheerful in most situations. I don't shirtk with the house and kids, although I could probably do more. I'm happy doing it, but tend to leave the planning and organisation to her.
I know that if I wasn't forcing the issue, she'd never do anything to try to change things. That's why I'm sceptical of any softly-softly long-term plan to reintroduce intimacy - she just doesn't have a vested interest in it, and I know that the thought of it is quite distasteful to her.
