Anyone sniff boys underwear?

I went the my friends house the other day and she has a really cute younger brother about 14 years old and while she was in the bathroom I went into his room and picked some underwear out of the hamper and pressed it to my face and smelled it. It really turns me on and I've once secretly taken a couple home with me to smell and put on myself to feel

does anyone else like to sniff other boys used underwear?
