Look, most of what you WANT to do is probably cringe. There's a lot of horrible shit out there, and nobody's talking about how embarrassing THAT is, compared to wearing a pup hood/running around on all fours/model railroading/writing Sonic fanfic/w/e harmless stuff.
The only way you'll avoid being cringe is sticking with what media tells you is appropriate for conventionally pretty cis people your age who are naturally athletic, like movies and who are pretty well off.
So why beat yourself up?
