My first con experiences have been very cringy for me, but I've only been to 2. I was never touched much as a kid, and almost all the physical contact I had was pretty abusive. Now I consider most physical contact really uncomfortable, I dont think I've had any physical contact with a human other than hand shakes, accidental hand touching passing tools, and a few incredibly uncomfortable old lady hugs at church things, for around 5ish years.
Morphicon 2009 was my first and I was still a teen. Kept having fursuiters randomly hug me, some were clean smelling but a few were really suspiciously musky. I freeze like a deer in headlights when hugged, it was pretty bad.
Second was one in boise Idaho in 2014, but almost no one would even talk to me. I was there with my then crossdressing passable boyfriend, who had ass length hair, a lolita costume, and a set of fox ears and a tail. It was pretty boring, no one wants to talk to a generic airman when there's a cozy femboy next to him. there weren't even any good pannels.
Sorry for walloftext story time. I'm incredibly lonely and bored.
