Weird Kink?

Hey guys I know this is probably weird but I think I have a brother kink?... my ex was a guy but for some reason i always wanted his brothers attention and to hang with his brother even though i knew nothing would happen between us. The same thing is happening with my new relationship. I’m 18 and my bfs brother is 20 and for some reason I’m addicted to spending time with my bfs older brother and idk why. I don’t want sex with him or anything I just like the attention. I like talking to him and we’ve exchanged secrets with eachother which I haven’t even shared with my bf. We have added each other on Snapchat and we sit on the lounge and talk together everyday after Uni for hours. Idk why but I feel like it’s a kink. Is something wrong with me?
