Stop it guys. LPSG exists to share the male body. Not to discuss their sexuality. It's none of your business whether he likes girls or boys! The first Shawn Mendes thread was closed because of people like y'all. And you didn't learn anything. Stop to decide what people are and start to live your own life.
Who are you to decide what LPSG exists for? The only reason his sexuality is debated is because he invites that debate with his behaviour. Don't tell other people what to do
