Namechanged for this because I'm a coward and I'm going to have to admit to a horrible aspect of my personality. I've been in 3 LTRs in my life before I met DH, and each time, after two or three years, I just lost interest in having sex with my partner. There would be a year or so of tension and very little sex, and then I left them, no matter how great everything else was. It's not that I lost interest in sex altogether, but just with that partner.
I'm now married with a DC - I've been with DH for nearly 4 years. I probably shouldn't have got married so soon, given my past, and of course I'm now back in the situation of just not being interested in having sex with him. But I don't want to leave this time. He's wonderful in every other way, he's incredibly patient with me, and he's not changed his appearance (no bad personal hygiene, no weight gain, nothing like that).
I used to fancy him lots, and our sex life was great before DD was born. I'm currently a reluctant SAHM (we moved for his job and there are no jobs for what I do here that pay enough to cover DD's childcare) and I'm still breastfeeding, so I feel frumpy and resentful and often pretty distant from him, but I just can't imagine suddenly fancying him again even if I got the job of my dreams. The only way I can get turned on enough for sex is by pretending it's somebody else, usually someone I had a FWB situation with a few years ago. Is that what I need to do for the next X years, or is there a way of making myself fancy DH again?
