Although I'm not a boy's paper, in my opinion, it's no problem for boys to tattoo their eyebrows, so what does it matter? You can tattoo your eyebrows if you want. Go your own way and let others talk about it. Don't care what others think, you just need to do what you want.
I got my eyebrows tattooed when I came home from the Dragon Boat Festival this year, mainly because my sister-in-law was learning eyebrow tattooing nail art and so on. Then she went back to the Dragon Boat Festival and saw that my eyebrows were very few, so she chose to tattoo my eyebrows for me. I'm happy, too. After all, I have fewer eyebrows, and I always need to draw eyebrows, but I feel troublesome. It's ok to tattoo my eyebrows without drawing them in the future, and it's more expensive, just because my sister-in-law won't ask me for money to tattoo my eyebrows. It's perfect.
In fact, I think everyone loves beauty, and so do boys. Although it is common for girls to tattoo their eyebrows, it doesn't mean that boys can't tattoo their eyebrows. There are no restrictions on men and women. At most, it's just a secular concept, so don't care. Eyebrows can especially reflect a person's spirit. Having eyebrows is completely different from not having eyebrows. I think you must be one of those people with very few eyebrows, otherwise you wouldn't want to tattoo eyebrows. After all, most boys don't like these things. But I think if you tattoo your eyebrows, you can solve the trouble of having no eyebrows, and make yourself look more energetic and handsome, so you don't have to think it's bad.
So I think you can tattoo your eyebrows if you want. You live for yourself, not for others, and you don't have to live in other people's words. Life is only a few decades, so it's better to do something you like.
