well to be fair they're both males, like yeah it's yaoiland but in the general u don't worry about that kinda stuff in real life as long as you're both the same gender like, I've had to change in front of my 5 year old niece all the time and we're both girls who cares?
Why is it a problem? He is a little child so it doesn't matter if he sees you naked. I always change clothes in front of my little cousins (4-5 year-old) and they don't really care
I know this is Yaoiland but for crying out loud,don't change clothes in front of a growing kid and show him your naked body.DAYUM (ノ_<。)
