It is OK for a man to shave his legs.
Although mostly women shave their legs it's perfectly fine and acceptable for a guy to shave his legs.
If you're comfortable as a guy shaving your legs then you should do so.
If you're wearing pants and have shaved legs then nobody is gonna know anyway.
Even when you're wearing shorts nobody is really gonna notice that you have shaved your legs and even if they do they are not gonna really care either way.
I shave my legs as a guy all the time and wear shorts in the summer.
Nobody notices or cars and even if they do it's their problem if they are offended by it.
Just like I cannot stand to have facial hair and shave it off.
I don't like having any body hair except for the hair on my head and even that hair can get annoying.
But if you want to shave your legs as a guy you should do so.
Don't worry about what others think as it's your body and you should do what makes you comfortable and happy.
