Self-care, diversified?

{Edit: Wrote a thing!}

So, I'm trying to get a little better at this self-care stuff. All the cool kids are doing it. However, based on a preliminary search and a venture into the blogosphere, it seems like all the How To Self-care guides and lists are by and for women.

I'm not a woman. I wear t-shirts and cargo trousers every day, I don't own a hairdryer, I haven't used conditioner in 10 years, I don't shave anything ever, I don't moisturise or use face masks or buy sparkly bath bombs. I literally ignore my skin and hair and they get on great. I don't drink wine, I don't enjoy movies centred on romance. I am into arty crafty stuff, but it's my main pastime and it doesn't relax me, so doing it for self-care isn't really going to help.

I mean, I am not one to put people in boxes, and for all I know the people writing all these blog posts are trans and/or nonbinary and/or some kinda queer. But whoever's writing these guides, they are really really not aimed at me.

So what's a man or a non-feminine woman or nonbinary person to do when it comes to self-care? I really want to get into taking care of myself, but I just don't know how to find any direction at all when every article assumes I feel better when I care for my skin, you know? I've been trying to find my way in this for months and I get bombarded with advice to rearrange my wardrobe or indulge in a naughty tasty treat...

Maybe helpful context: I'm nonbinary, autistic, have EDS and OCD.
