My boyfriend said my butt was small

Savannah

My boyfriend and I have been together a year and a few months now and the entire time he has not shown any signs of disliking my butt// thinking it’s small. He will grab it all the time and I never thought that he would say it was small until he did just that today. I had sent him a few pictures of my butt in some new leggings I bought because I thought it looked good and today I asked him if he thought my butt was small because of his reaction to the leggings picture and he said “just a little bit”. Not only was this embarrassing for me because I was telling him about how I thought I looked good in those leggings, but it made me feel kind of insecure. Later, he apologized and said my butt was perfect the way it is and he liked that it was just a handful but I still can’t get over when he was being truthful. Is this normal for a boyfriend to say?
