Shounen Ai or Yaoi?

So there's a webtoon(it's called our companionship) I'm reading on here, there are around 40 chapters, and someone put the yaoi tag on it cuz of 1 sex scene out of all 40 chapters, I checked 10 other websites, they all said it was Shounen Ai, and the scene wasn’t even explicit, you can only see from their chests up, everything below that was covered by a black square, now is it yaoi or Shounen Ai?

Note:
Yaoi is a Japanese word, which is actually something of an acronym. It comes from "YAma nashi, Ochi nashi, Imi nashi", which means "no climax, no point, no meaning".
