I am a fashion designer student, in the top five of my class. I also work part time at a place that has a good environment and good colleagues. It is just that there is a female superior who wants to have some kind of relation with me. 

A little bit about me: I am also a model (male), 25 years old.

So what do I do about this superior of mine. I just don't want my promotion and other things in jeopardy due to that. I have no problem with having a relation with her though and I wouldn't call it sexual harassment per say but my friends think that it is heh. Just wanted to ask professional opinions of you guys here. Thanks in advance for the answer.
