No, Erik Shoji is not gay. First of all, many sources have claimed that he is dating a girl, Sydney Yogi.
Currently, which directly dines all the rumors of him being gay.
However, when we looked over why the rumors were spread, it seemed like a social trolling issue.
Erik is considered a very good-looking person, and people are great fans of his looks.
Despite being so good-looking, he did not have a girlfriend, or at least he did not reveal that he had one. So, people started to make jones stating he might be gay.
As per our observation, it does look like this is the case, but this is not an official claim either because Erik has never mentioned anything about his sexuality.
More regarding his partner, she is a medical professional and a doctor now, as seen on the post by Erik. Well, she is also a volleyball coach, apart from just a physician.
