Is it normal to have a same gender coworker who really likes you?

I am 8 years older than her , she thought I'm 22. I'm quite curvy. not skinny and not skinny. and she's very skinny.

she ever told me that most women body aren't great , and she compliment my body,.. but she loves to call me chubby,

she likes to touch my belly, tickling me, hugging me from behind, even climb on my back and, hitting my arms playfully.

to me, she doesn't look like lesbian... but she's quite tomboyish
