I know what you mean but that is how I feel after having the baby because of the flabby tummy and fatigue. Though while I am pregnant I feel so sexy because it is the only time that my boobs are big and my tummy is rock solid. I love being pregnant!
I have learned over our 15 yrs of marriage that just because I don't "feel" like having sex does not give me the right to deny our marriage that intimacy. If you truly love your hubby and want him to feel loved,adored,appreciated and sexy then go and be with him. He loves you so much and wants you...stretchmarks...cellulite...blueish veins all over boobs and belly(and God knows where else) and all. You need to get passed the image that YOU are desiring and love the fact that he wants YOU. You don't want him to suffer...so be with him..initiate it. You also don't want yourself to suffer and that is what happens when you think you're not pretty,sexy or slim enough. Feel sexy knowing you two created this little life growing in you. Go out and get some exercise daily...get sleep...eat healthy...drink plenty of water and take your vitamins...those are great mood changers.
Learn to fake it better. Explain to him how you feel but let him know you need his help by rubbing your back..doing dishes before bed...giving you some time to unwind and then shower and then be ready to love on him. Then ask him what he would like from you. My hubby knows when I am not in the mood but I do become an active participant and am always very happy afterward. ANd then there are times I am more frisky and more of the initiator. But..he is grateful for either way...and he loves me so much for always being game.
YOu are not alone. Most women are not programmed to be sexual tigresses. I had a wonderful OB/GYN that explained to me after my first(everything was soooo new) She told me that it is a mother's nature and very primal to not desire sex during and especially post partum. THis is the body's natural tendency to do everything possible to keep that baby safe and fed and alive. Hormonally your body does not want to be pregnant again and knows it needs time to heal. Your instinct is to be a mother bear and you are constantly subconsciously thinking about the baby. Sooo, the thought of sex is not a strong desire.
But we know how important it is to nurture the relationship so we talk ourselves into being intimate. I was grateful she talked to me about it so it made me feel normal. But she told me this was not reason to deny our marriage intimacy...she said you have had 6 weeks...now go home and be with your husband...he is probably climbing the walls. Dang I love that doctor...she was great. I kept her for all 3 births..
Good luck and best wishes for a great pregnancy and at becoming a better actress!
