Husband does not find me attractive anymore

I dont think my husband finds me attractive any more. Bit of background, weve been together 10 years we have a 1 year old and have been married about 2 months. The last few months my husband has only started wanting sex 1-2 a month as previously it was 2-3 times a week, i feel like im constantly getting turned down by him and its embarrassing. Weve always previously had a good sex life even after having our daughter so its nothing to do with having a baby or anything. But i started to feel like he wasnt atttacted to me anymore because he doesnt want to have sex very often and when be does i get the feeling its just because hes in the mood to have sex not becuase he cant keep his hands off me or anything like that. When we are having sex he has no problem getting an erection but its like we have to keep stopping so i can get him more erect. I.e like when were having sex hes not very attracted to me so its an effort to stay hard. Weve just decided to start trying for baby no 2. Ive wanted to for a few months but not pressured him at all , he said he wants a second but just not sure when so ive just said just let me know when you do. When i was at work yesterday he text me saying lets try for a baby later, so fast foward to that evening i put on lingerie, full on basque, suspenders,thong (hes always loved that kind of stuff) walk into the room he glances up for a second says hes not in the mood and goes back to watching tv. I stood there for a few minutes just talking to him and he didnt look back at me once, like didnt have the slightest interest in me in lingerie. I just feel like if a man sees someone attractive in racy lingerie, even if hes not in the mood for sex, he would still keep looking at her in it because he finds her atttactive in it. I feel like if an attractive women walked in the room in that sort of stuff he wouldnt take his eyes of her. It just made me think he must not be attracted to me anymore and i dont know what to do. Theres no problem anywhere else im our relationship and i know he loves me and we're husband and wife and we have always had sexual chemistry up untill now. I just dont know how to fix this, i just feel so unattractive and have lost all body confidence. Sorry its so long.
