Would you do this or not?

Hi, so my coworker and I where seeing a video of a girl that dances/twerks, she does music challenges, dancing new beats and she shake her body like a snake literally lol, and I told my friend wow she is amazing I will show this to my boyfriend and see what he says, and she was like are you crazy, I rather dance for my boyfriend like that but never show him the video,

Do you think that is bad for a girlfriend to show her boyfriend other beautiful women on social media, at malls, restaurants?. I thought this to the contrary makes us look secure of our self’s. My friend is totally against this. She says That showing beautiful women to our man will only put bad thoughts on their heads and make us look underrated.
