Would you?... c'mon be honest, i need ladies input also. I am not the finest dude out there, but i think im ok?

Ok, i am 20, my boss is like 40... and she is HOT / BEAUTIFUL (don't get offended ladies ;)... anyway I get the feeling that she flirts with me a little. For example she stands right behind me when i am sitting in my chair typing... like right behind me... like if I lean back a little her HUGE would cushion my head, and she did that the other day and was showing me something and put her hand on my shoulder, while talking to me like nothing weird was happening. I gotta say I was so scared to move because she's my boss u know? What do you intelligent readers think i should do? I'm sure you can guess what i've thought about doing... tee hee!!
