Struggling to get horny

I hadn’t seen my boyfriend in months then we finally spent the weekend together. The whole time i wasn’t horny but it was fine bc we weren’t doing much. Then one day we finally decided to get frisky and yall, my horniness was non existent. He was kissing my neck and sucking and rubbing my tits and NOTHING. I wasn’t even wet. All of my moans and gripping him with my fingers were fake because i wanted to seem like i was enjoying it. Eventually smacking and grabbing my butt stuff turned me on but it happened after SO LONG. Why? Am i broken or does this happen to you guys too?
