Felt his dick on my back?

I was with this guy and we were cuddling on my bed and at some point we ended up in a position where his legs were open and I was laying between them with my head rested on his stomach/chest. I didn’t initiate the position I just complied I guess. I felt his dick on my lower back and I know he felt my back on his dick. We didn’t acknowledge it or anything we just laid there like everything was normal. Is this a normal thing? do you think he wanted me to feel it, or am I overthinking it?
