I had the same reaction when first I saw the sculpture. Too pretty, to effeminate. But, then I investigated further and found that in hellenistic art and well into the Roman empire, the satyrs got pettier and prettier until they resembled pedophiliac pin ups. As Praxiteles was at the begining of this trend, it is not an impossibility that the figure may have been meant to be a satyr. I think it unlikely, but it is not impossible. I too would love to know the source of the suggestion that wrestling competitors wore a headband with a thorn in the front center. I have done a lot of research and can find no reference to it anywhere. I know many statues of wrestlers and gymnasts, but this is the only figure I have ever seen with that attribute. I must reiterate that it is not a possibility to understand a sculpture from photographs. Without seeing and carefully examining the object in person, it is interesting, but idle speculation at best.
