I know I am - I'm married and it's very unfair of me.
But to be truthful, dh isn't very good at satisfying me, he has never bought me to orgasm, and I end up faking to get it over with. 12 years of doing this and I cannot be bothered with it.
I can feel the lack of sex pulling us apart, and although he doesn't mention it I know it's a big issue for dh.
I've tried talking to dh about what I want, I've tried showing him and I've even tried toys. I've done all sorts of things to him over the years to try and excite things but ultimately sex to him is a fondle of the breast, quick rub down below to try and lubricate things and in he goes and I play along so it ends asap.
Since the birth of dd2 7 months ago, sex is non existent and I know dh is making attempts to get things back on track but I dread it. We are only in our thirties 
Is the end of our relationship?
