Is it weird in the men's changing room?

Been going to the gym in the mornings lately and would tend to shower in the men's changing room to get ready for work.

I get dirty looks from middle aged men whenever i apply body lotion after shower. Do they just have an unhygienic dirty men mindset or is it frowned upon to do it?

nonetheless, I dont care other people around me think but would like to be mindful if there is some sort of 'men's changing room' etiquette.

Edit: It's Body Lotion.. god i'd be some psycho if i was body motion HAHA
