Boyfriend is never horny

So my bf and I were talking once and I asked if he he thinks sexual thoughts about me and he said “no” and I feel weird that I do have sexual thoughts and I masterbate thinking about him cause it makes me feel like I am a bad person cause he seems innocent and recently he has been kind of ignoring me I’m worried that our relationship is drifting apart because I’m to open with him cause we have only been together for 2 months.
