What things could I do (while wearing a blackbird fursuit)?

You could go to conventions. Unfortunately, it is illegal to wear 'masks' in public, so you'd probably encounter negativity or even legal issues.

If you could breathe well in it, you'd be able to wear it as long as you wanted. Don't do it until you black out from heat/lack of air/etc. If you had to go, then take it off.

Technically it is greater of a "paraphilia" than a "fetish". in elementary terms while it is not in elementary terms for relaxing, however the only way a man or woman can get sexual delight, might it then be seen a fetish. who's brave adequate to settle on what's "generic"? all of us have our very own little fantasies. that's a reasonably harmless prepare on the dressing up point, and if accomplished via 2 consenting adults, maximum questioning human beings might locate it stressful to label it "odd". for my area, it would in elementary terms grow to be odd if the animal play in contact non-consensual scuffling with and biting, or the completed domination of one man or woman via the different.

stand on top of your houses roof and squawk super load at the top of your lungs while flapping your wings. (neighbors love that)

just wear a diaper.
