I don't think bashing the DH is helpful IF the DH isn't demanding, there's no crime in being horny, but the quality of sex is dire, and for that he IS BU because it sounds like a one way street.
I'm gasping, but DH has sciatica, I may be guilty of lamenting how much I miss him, but right now, it's not going to be 'great' every night.
I am however very understanding that DH is pretty limited in what he can do for me, so because I am getting it all a little easier at present the oweness is on me to try and make things a bit better. I'm not a bitch for wanting it, I would be VERY unreasonable to simply mount DH, please myself and then carry on complaining. Likewise, he wouldn't be helping himself if he just allowed me to get my oats. You are enabling your DH to remain lazy.
Flip it and your DH is being unreasonable for not actually thinking of YOUR needs a bit more, it doesn't make him a wanker, but just unreasonable.
Likewise you are being unreasonable for perhaps not demanding quality?
Saying all that quality sex is rather difficult with a restless baby in the house, so perhaps you need to sit down and TALK, arrange something (that he contributes to) that would make it easier for both of you to really enjoy each other.
