Don't know whats wrong with me

So me and my husband have been married for a couple months now. When I met him I knew he was the one and we fell in love instantly and he made me realize what a true soul mate really was. We have an amazing sex life together but lately I've been getting this feeling that he doesn't love me and/or want sex regardless of any reassuring he tells me.. he tells me he is not used to being the pursuer and neither am I so he has agreed to fix the issue by being straight forward about wanting sex. But lately I become frustrated because I find myself wanting sex and wishing he would pursue me and when he doesn't I get this depressed feeling that he doesn't want me anymore, but my question is why do I feel like I can't just ask him for sex? After all he is my husband. You would think it would come easy, after all we married each other and made a commitment together. I love him so much. I feel like I'm ruining our relationship arguing about not having enough sex. Does anyone have any suggestions as to why I'm not able to just come out and bluntly say I want sex? Any suggestions I would appreciate. I really want to fix this problem I have because he seems to think there is no problem but I hate feeling this way. Feel free to ask me any questions to better understand or help me. Thanks!

So I slept on the couch the night I wrote this bc I felt so bad and stayed up all night researching things and thinking about how to resolve my problem bc I know it's not his fault and bc I love him so much so by the morning i felt so bad about not sleeping in the same bed with my husband i said what the heck, he's the love of my life, he loves me so im gonna go crawl in bed with him!(naked...hehe) i put the ball in his court. I thought if this doesnt do anything idk what will lol. So we cuddled all morning and when he realized i was nude, i asked him later what he thought and he said "sexy time!" So i felt great i put myself out there, and he acted on it. So I wasn't frustrated or depressed, and I feel like he wanted sex just as much as I did. I was straight forward about it and it worked! Thanks ladies!!!! For listening and giving me advice!
