Body language on a first date is he interested?

On the date we attended a Christmas market outside. We sat in the grass and he laid on his side with his whole body facing me. I was turned on because he I could swe his chest and his package area, I tried not to look there though ๐Ÿ˜†. I sat crossed legged towards him. He seemed very relaxed sprawling out and displaying his body. Thoughts?
