I think this will effect me and my husband longterm

My husband doesn't have sex with me as often as I'd like. I'm 25 and he's 31. I think I have settled down too early and maybe should've had my fun but I did it for religious reasons and because I loved him very much and seen myself spending the rest of my life with him. We've been married for slighly over a year now prior to knowing one another for 6 to 8 months I think.

So....

Tonight I asked my husband why doesn't he have sex with me much anymore whereas in the beginning he used to initiate it often but I struggled with vaginismus at that time. I asked if he was attracted to me, he said yes he is and if he wasn't I'd know because he'd avoid being at home. He said he just doesn't think about it and in the beginning he did a lot more but now not so much or barely. That hurt if im honest. He told me that men tend to become like that after being with a woman for long. I asked him if im shit in bed, he said no to that as well. He said when he doesn't see me for long then he misses me and then does think about it. But he said he is attracted to me and I know he loves me as well. I'm wondering do men tend to think about sex less when they've been with a woman for longer than a year? During that conversation I was okay but some of the things felt hurtful like when he said he doesn't think about it and I asked if his.sex drive is low I didn't get a direct answer, other than its up and down. After a while thinking back at the conversation i feel like he basically doesnt think im hot enough for him to want to bang all the time. He told me men arent horny all the time, in the start when they meet a woman yes but after that it dies down. Im wondering if anyone has had similar conversation; what happened? Im feeling like mine doesnt really care about sexually pleasing.me even though when we get intimate, he does focus on me as well so i dont exactly think its that. I think long term tho this will become a problem for us but I know I can't make him have sex with me that's not right it's his body. He said we can schedule to have sex and that he will mentally prepare for it so it'll happen...he has been cheated on 3 x in the past by 3 different girls and I'm thinking this may be the reason...it's never right to cheat anyway though. I think I'll probably just stop initiating...I see posts from men on reddit for example wanting sex from their woman and they don't get it often even though they've been with their woman for long...so idk maybe all men are different. I did say this will.be an issue for us, and he didnt say anything in response and i cleared it by saying im glad we had this chat. I do miss feeling wanted sexually if im honest. When were both off i always seem to.be on my.period though or im sick, so we couldn't properly have sex and he told.me that sex isnt exactly relaxing for him and he struggles to sleep so he prefers to just do other things. He is a detective in a police force and works with complex cases so i do sort.of understand.
