Arrggh. Not sure how to start this, I feel disloyal even thinking about it.
DH is lovely, kind, considerate, good dad, good partner, and I fancy him. Been together 15 years so no mean feat imo!
But... I don't feel desired by him. We have sex about once every 3 weeks, mainly instigated by me. He has a stressful job and is overweight (as am I although not as much) and just doesn't seem to have much of a libido. He's never been a three times a night man, but I feel as though he's too lazy to really bother. Or actually, maybe he'd just rather be doing something else? 
The upshot is that I want to feel desired, and am looking for that from other places. Would never have an affair, but I am starting to want male attention and being a bit more flirty. Frankly I don't know what's wrong with me - I haven't looked at another bloke since I met DH and put it down to a mid life crisis, at 42, but I don't think it is. I think it's because he doesn't make me feel good in that way. Which isn't his fault, my self esteem shouldn't be based on DH's actions. I'm a grown up so I know I am being utterly unreasonable.
It just makes me sad and I wondered if anyone else feels the same way
And if anyone has had this in their marriage and come through it?
