Guys, How you a guys feel when a female touches your hips?

me and this coworker always poking each other hips or stomach. One time we were walking down the stairs, told him to walk faster but instead slowed down. I was behind him, so I just grabbed his waist and kinda pushed him a little so he could walk down the stairs. He didn't flinch or anything. I did again later on more likely on a different day just cause I was behind him again, but this type he said "I wave my hips back and forth"
