Contact again or not, I've had cases where is was welcome and cases where it was not.
Going back to the original post however, I see several red flags. He went for a massage and was upsold several times. He said he wanted to "own" you. And contacts you again the next day.
You may have gone along and you definitely enjoyed it. You may have gotten off on his talk, he could have been reading signals you were sending.
All together, with the upselling it seems he saw you as someone he could manipulate and push buttons for more money. Okay as long as you're a willing participant.
