Is it normal to enjoy the smell of other guys armpits?

I love the smell of other guys armpit, I can't help but to get a whiff. I don't stick my face in their armpits or make it obvious that I'm smelling them, but sometimes I can smell their deoderant on them. The best smell is armpit in the morning, when the nights before application of deoderant is fading and a hint of man musk is detected. That just turns me on! I can't help it. If a guy would lt me stick my face in their armpits and just breathe under their for minutes on end, I would. I also enjoying liking my partners armpits during sex, its like I get a high off of it. Is this normal?
