dont faint at home with things i do outside?

hi so i have vvs (duh), i've strugged with it my entire life but something that confuses me is that for example , im a huge fan of greys anatomy and watch it all the time. obviously its bloody so i thought i'd have a reaction to it, but i dont at all, unless i'm watching it outside of my home or my bfs home.

it could be that im comfortable so i dont have a reaction, but i'm worried about passing out in public so i have a bigger reaction.

is this normal ? thank you!!
