I recently saw a guy at the gym doing what's often called a "girl" push up.
This is just my opinion, but calling something a "girl" thing because it's perceived as easier doesn't make any sense. Going the slow and easy route doesn't diminish your progress, like when I do assisted pull ups in order to help me to do more unassisted pull ups.
Don't be afraid to do an exercise just because people say it looks "girly."
