Back when I was 11 and my best friends older sister was 18 I went over to her house with some other friends. And when we were in the living room chilling, said older sister came down to get something and her mum told her to cover up more cause she had on a top where you could see the top of her bra and I kinda just looked away cause I didn't know why I was so flustered by that. I now have come out to my friends as bi and am a bit older now (still a teen) and my friend's older sister is older than 21 so she is an adult and I am still a kid. I've been thinking about it lately and idk is it weird? Is it just like being a kid and having crushes on celebrities? Am I sexualizing someone?
