DH and I have been together ten years, and have three DC. The youngest is three. I love him very much. He's my best friend, a brilliant dad, a supportive and affectionate husband and I trust him completely. I can't imagine not having him as my partner. BUT I don't fancy him.
When we got together we had chemistry. Just sitting next to him was exciting! But it's been ages since I felt like that. I have a fairly low sex drive and have been celibate without feeling deprived for fairly long periods before I met DH. In previous relationships I lost the spark too; it just seems to be what I'm like. I have no interest in any other men, and haven't since we got together.
We do have sex, and I am totally emotionally consenting, just not really that bothered physically. I find minor things like morning breath a barrier and get more turned on when I'm drunk. I know DH would like sex more often (currently I reckon it's 1/2 times a month) and I'd like to rediscover my enthusiasm. I daren't tell him how uninterested I feel as he would be horrified and hurt, and the disadvantages to me are not enough to justify that. I also feel unattractive after three pregnancies/weight gain/lack of time for grooming etc.
Sorry this is so long but has anyone else gone through this and found their spark again?
