well...hmm I used to hide it very well so I guess I can spare some tips
Im usually on TFF on my pc when no one is home or Im on my phone
I would only wear a tail at school or in my room
I would hide my artwork from my family because I started drawing anthro
now in terms doing things furry related like zeph said thats a different thing
Im 15 so I have not yet gone to any cons or anything super fun like that but I do play xbox with other furries so thts about it
