Plenty of men wear makeup. Embrace your inner goth.
Personal note: this is one of the many gendered things I simply refuse to acknowledge as gendered. There are plenty of instance where it's perfectly normal (thus mentioning goth) and it shouldn't be gender specific to want a more uniform completion.
Cis straight white male here (Though I am Aro...) I color my beard, and I wear some eye shadow occasionally, have done various things with makeup, its a fun time!
edit: By "color my beard" I mean big, vibrant colors, not like "I'm greying and color it to avoid looking like it". My favorite combo is Green on one half, and Blue on the other half.
If you decide to color I highly recommend Mofajang hair wax, rinses out immediately, stays for as long as you don't rinse it out.
I've bought most of their colors, so I can mix and match and do crazy things with it. My wildest was a sunset from top to bottom, black and stars on top, dark purple, then lighter and lighter to sky blue on the bottom.
I assumed as much but I still find it a bit silly that it's explicitly a gendered act when it's used by professionals in many fields. If you want to be flagrantly neon pink lipped, I really don't think of all things gender should be the measure of if it's alright.
