Idk if it's me, or him

So my boyfriend and I haven't been dating long and at one point, I asked if I turned him on. His response was that it wasn't in the way I was thinking, instead he said he felt a great/real feeling for me. I wasn't exactly sure what that meant considering guys get turned on by almost anything. My friend suggested that maybe he was asexual. Maybe he was just trying to be respectful, but I'm not exactly sure and I don't want him to think I only want sex.
