On MF, the one with the best sports/deep tissue kneading skills is Dario. He is not only strictly therapeutic, but also requires *full draping* or client to wear his underwear without draping for the entire massage, neither of which I care much for. However, he is a personal trainer and knows how to give a legit deep tissue/sports massage: https://www.masseurfinder.com/massage-therapists/15341/
Ian is a straight masseur that used to massage in nude with no sensual elements whatsoever (and wouldn't allow touching) but he has since changed to strictly therapeutic and does not even massage shirtless. I accused his RM ad to be a misleading/falls advertisement with all of his shirtless photos with his decision to go 100% therapeutic to which he never commented: https://rentmasseur.com/masseurian Like Dario, however, his kneading skills are top notch since he is also a weightlifter.
If you want a-OK/mediocre kneading skills with extras, PM me and I can share them with you.
