Guys, What snapchat filters do guys use if they are gay?

I don’t have a problem with gay people but say I’m interested in a guy but don’t know if he is a gay. I noticed this guy I’m interested in he took a picture with the pink heart filter on Snapchat and posted it online. Also everyone including myself is in the age of 21 to 24 in this particular situation.
