Is it normal that I lick my phone screen of pictures of girls?

I did that once. I came to the conclusion that having a picture of a girl on the screen did not cause it to taste like an actual human female. Once I had learned that my device would always taste the same regardless if what was represented in the pixels of the screen, I never licked it again. Now, brother OP, you must have learned this as well. Join me in enlightenment and stop licking your screen.
