If you have access to IG, you may find it interesting that NYCViking has an extensive profile on there using exactly the same name there as on his escort ad. Through various social media, he freely uses his escort name - suggesting that he wishes his escorting activities to be out there in the open to his followers and friends. As a self-described queer nerd, with 9,000+ followers on IG, he seems to be well known in NYC.
Overall, a very nice guy and a positive experience.
