I live in a gay village for almost 5 years so I'll try to answer. Some gay people will be obvious in the way they talk, walk, etc... But some others talk, walk, move just like straight guys so it's hard to tell until they let you know... But then again, there are some straight guys that seem gay as hell so everything is confusing in my town. There are guys that had surgery to have boobs, butt, and everything to look like girls but they're straight and kept their shlong because they're still into girls while wanting to look like a girl. They're like incompleted straight transsexuals but they don't want to be called transsexuals (or tranny), they wanna be called straight men. Some are normal straight guys by day and drag queen by night. I have so many stories here that are gonna seem weird to you but at the end of the day, it's just better to not think too much into it... The obvious ones (like famous Youtuber James Charles) have the stereotypical way of gay people that you can spot a mile away but there are a lot of very discreet ones out there we can never spot until they say so.
