Is it normal?

When my bf and I first got together, he was very affectionate. Always wanting to cuddle, touch me, hugs, kisses, all that good stuff. Now he hardly cuddles me at all and when I approach him for sex, he shoots me down almost every single time. Although we do have sex probably 5 times a week, it’s always when he wants to. (I do too but I take it bc I feel like itll be my only opportunity if that makes sense). He never would’ve done that when we first got together (been together a year). We now live together. I’m just wondering if it’s normal for a partner to “lose” his or her want for most physical affection . I know there’s a “honeymoon” phase but idk if it’s real or not bc I still feel the exact same way I did when we first got together.
