I've had massages from Kostas, and they were great. I think there's a difference between "sensual" and "sexual" or "erotic." I've experienced all the things the OP describes, which felt sensual even though I knew things weren't going to go further into sexual or erotic territory. And that's fine with me. There are other places for those kinds of massages. The important thing is that the massage itself is fantastic, and he is an absolute sweetheart in addition to being easy on the eyes.
