How does your husband feel about all of this? Has he tried to put you in the mood more often?
Im sort of going thru the same thing with my live in bf. We used to have sex a lot (i used to keep track for fun and it was 50-60 times a month) and now he's lucky to get laid once every 2 months.
My problem has just not been getting turned on and feeling desired. I have low self esteem and love attention men give me, but for some reason I cringe when my bf tries to touch me. I think I miss the adventure and intensity of the passion and lust two ppl can have when they first become intimate (we've been together a lil over 9 years now).
Maybe if he showered you with affection more and tried to do things that you find erotic (whether it be watching porn to sensual massage) you would be turned on more?
Its maybe worth a shot.
Good luck =)
