Is it normal that i like the smell of my own armpits?

When I am home alone, sometimes I like to smell my own armpits. I like the smell even though I don't wear deodorant.

Just so you don't get the wrong impression, I am a clean guy and shower every day with soap and shampoo. I take care of my body and my skin, apply moisturizer etc. A woman I was in a relationship with even told me my smell turns her on and asked me to stop using body spray, which is when I stopped.
