What did he mean when he said this?

Me and the guy I like were texing each other and he wanted a hot pic of me, but my retarded phone wouldn't let me send it, so I I told him that I would make it up to him, and he told me "i want u to make it up to me but how"and I told him thats for me to know n u 2 find out and then this is what im not sure what he meant he said "U want to in out with me" did he mean or something else?
