What Could Parotid Glands Under The Ear Suggest?

Hello, I wanted to know if it is normal to be able to feel the parotid gland under my ear and around my jaw? I can feel the on both sides, one being a slight bit larger than the other. I am a 28 year old female with a slim build I am 5'7 and around 118 lbs. Is it normal to be able to feel this gland? It is only really noticable when I have my head tilted toward the back or when I turn my neck from left or right. It is causing no pain at all.
