He prefers sex when I wear makeup?

The other day me and my boyfriend were texting and I was getting ready to go to his house. He asked me ‘are you gunna wear makeup’ so I said idk why? And he said ‘I like sex a lot more when you’re wearing a full face of makeup’. What does this mean? It hurt my feelings because it feels like he’s not as attracted to me when I’m without makeup. I don’t feel I need makeup to look good, but I’m a MUA and makeup is what I do best. He’s really knocked my confidence. What does this mean?!
