AIO? Is this a normal response from him??

For context, we've been talking for about a week and a half. We started just texting, then a couple phone calls just getting to know each other. Sexual topics did come up, as we both agreed that's an important part of a relationship also. Then when he says this and I try to make light of it, I found his reply really concerning. Does his response make sense? It seemed totally unrelated to the topic, so I'm worried I started reading too much into it. Can anyone explain his point of view in this convo??
