This may be unpopular but
Just by looking at someone you cannot tell
If they are gay or straight
If they are bisexual/Pansexual/Omnisexual
If they are Trans or Cis
If they are allosexual or asexual
The ONLY way to be sure of anyone's Sex, Gender, Pronouns or Orientation is for them to tell you, you can ask but they do not have to tell you.
If you make assumptions about any of the above, you have to expect that you might be wrong.
