Okay guys here's one for you. I used to have a friend that happened to love the smell of armpits. I regularly let her nuzzle mine.
Why did you let her do that? Did you reciprocate?
It's just that I'm not attracted to pit sweat. Her living near the subway line makes her smell particularly strong.
People get turned on by a wide variety of things, and if both parties consent and are of legal age, it's OK. Is smelling armpits something that you would reciprocate?
No one said anything about reciprocating! She was just interested in my pits. It's not like she was going to bathe me or anything.
It's fine to not reciprocate someone's fetish. Just make it clear to them that you are not interested in the same thing that they are interested in.
