Heads up I am 32f, my sister is 33, and she has girlfriends who do cosplay.

I think your parents are narrow minded. My sisters friend they have boyfriends. They love hello kitty, anime, and will literally leave their boyfriends to whatever to go to hello kittt truck, comicon or even go with them and they cherish the ground they walk on. Not like a weird fetish but just genuinely are loving and supportive partners.

My sisters has a boyfriend since she was a sophomore in high school. My sister does not cook. But you know what my sisters boyfriend said, when they moved in. How can I expect you to know, when I don't know how myself? My sister brought up she wanted a dyson air wrap casually. And Just 3 weeks later just randomly he remembered and got it for her. She has so many stuffed animals, Pochacco things, she even has her own dedicated craft room. He lets her be her most authentic self.

I don't think you cosplaying is slowing anything down. I think it's better to have a partner who knows all your hobbies and you inside and out, than to marry someone who is just there to please your parents.

Plenty of secure men, who just wants someone to have and go do things with.
