My boyfriend shared my nude photos with his brother

My brother and bf are good friends, I found out that my bf showed my brother some of my nudes. Its fucked up but it kind of turns me on knowing he's seen my body. My brother mentioned that for a girl with a dog face (his version of harmless banter) i sure had a nice pair of nipples. I asked how he knew that and he laughed saying he also knew i had a freckle on my pussy lip. My bf is the only one with pics like that so I immediately knew it was him. Since then I noticed my brother looking at me different and tbh I like it.
