well 2fatto, if you have lost your interest in sex, you have definitely got a problem with your libido. this could easily be because of work pressure and/or daily routine. women are under so much pressure these days with all the stresses of work, managing a household, having a husband or b/f, outside interests, etc.
don't feel like you have to "label" the problem though, you should focus on the fix. maybe take time out of your day every day (even if just a few minutes) to relax and focus on you.
when you are with your husband, take the time to make him feel appreciated by you physically, in other words, give him a hug, or a kiss or just look at him eye to eye and think about how much you love him. tell him. chances are that if you can get past your day-to-day stress, and focus on what brought you and your husband together, you can fix the issue on your own.
one other thing that may help is to dress a little sexy. pick out a real pretty new pair of panties and a matching bra. put them on and you feel sexier. allow yourself to contemplate that during the day and maybe by the end of the day you'll feel more in the mood to do something. there's nothing like wearing old panties and bras that MAKES me feel unsexy. the biggest thing about this is doing it for YOU not for anyone else.
i don't know what to say to help you, i just hope that something i said can help. i hate it when nobody has responded to someone, and i've not been in your shoes, but i'll say a prayer for you and i hope that you start to feel better about things.
