Me and my ex strongly disagree on this. Our son is 15 and has been in dance for a very long time and on a dance competition team. When he has a solo he gets a lot of acro dances because even though he's the only boy on the team he's the second more flexible. He's always been flexible but when he was much younger in dance he also took yoga and still does yoga to help keep his foecibyand he's only gotten more flexible over the years. He can bend his body all the way back where both his hands and feet are touching the ground and can bring his leg all the way up to his head. Don't really like that because he bites his nails and since he can do that he bites his toe nails and I find that gross lol but I don't think anything is emasculate about a boy being able to be extremely flexible. My ex already made it clear he's ashamed that our son even dances since he only claimed our two oldest who play sports at his job but they know he has a third son now. How this came up was my ex had his weekend with our son and he went to a BBQ and someone asked my son about cool things he can do and he said "I can do this" and did a perfect split and was able to put both legs behind his back. My husband said he doesn't want people to think he's emasculate because it's not normal for men to be that flexible. There's nothing emasculate about what your own body can do.
