No strings attached kind of relationship? Is it worth a try?

I dated with a guy that I thought is looking for a serious relationship. He was a gentleman on the first date. Then we had our second date unexpectedly because I happened to be near his area. We ate and chatted a little bit, then when he brought me to my car. He asked me if he can kiss me. I said, yeah sure. Then he said that "are you okay if we get more intimate next time, but please be careful not to fall in love."

I was shocked at first because I didn't expect that I am seeing a guy who only wants sex for the first time. I said, "Okay, I'll try not to fall."

I'll be honest. I am attracted to him and kinda emotionally attached. But I think I can put aside the emotional attachment and maybe try even once.
