What side is gay on the lip for the labret?

Okay so I gotmy tongue pierced and you know the typical stereotype guys at school said I got it to give better head, which is not true! (I got it because I wanted too, because I liked it) so going back on with the typical stereotypes, I got my bottom lip pierced, I wanted it on my right side but my piercer told me I should do it on my left because I have a natrual monroe on my right upper lip and he said it wouldnt look good, so I though about it and decieded he was right, so I left him do it on the left side, so this boy in my spanish class said are you gay? And I said “no, I have a boyfriend.” and he said “oh, so are you bi?” and I said “no, y?” and he said “ oh sorry its because you know people say when you get the left side of your lip pierced it means your gay.” I could have sworn it was the right side though, I mean not that I care in the first place because thats the side I was gona do it on anyways, but I’d like to know the typical stereotype, “what side is it that means your gay?” (because if someone tells me that again and its actually on the right side that means its gay, I’d really like to make them feel stupid and tell them it doesnt matter anyways),… So anyways, restating my question, “ what side is the “”gay”” side for the labret?”
