Many crushes

I can't make up my mind and I ended up having a lot of crushes even though I know there's no chance between us. So uh a lot happened this summer and when I got to see my half crush he was so much taller now and he was standing behind me while lining up for the cafteria but when he went to reach out for the spoons and forks which were next to me, he went in front of me and I could feel him.. uh sorta. Let's just say- is it normal to like the natural scent of the opposite sex? Like he smelled like he was sweating a lot but got cooled down by the air conditioning so yeah.. It's just me and he wasn't wearing any cologne or deoderant or whatever, just smells like a guy.. and I kinda liked it.
