Hi KrisRenee
Only you can decide that in the end, however I would say keep it because, I have always had long hair and always have since I was 19, I'm just like my mother, she has always had long hair as well and you know the old saying "like mother like daughter"
But as others have said what does long hair have to do with gender if you like long hair as guy, then have long hair.
Long hair forever.
Kind regards
