Is it normal that i keep looking at girls at the gym?

at the gym i goto there are alot of pretty girls and young women who workout there and they all look so sexy, fit, healthy, athletic, beautiful, some have their hair down, some have their hair up, most of them wear either tight or revealing clothes, alot of them wear makeup too, they come in all shapes and sizes like petite, skinny, tall, curvy, and i love when they make workout faces when they're breaking a sweat it reminds me of sex faces with the energy and intensity, i get soo turned on when they sweat and their faces look shiny, and i can see the wet sweaty marks, their butts usually look amazing, their attire accentuates the chest area, and i imagine sniffing their shoes and licking their feet.
