Yes men + women can be friends, though unless one is gay I believe there will always be some sexual tension in such a dynamic. Just my opinion however.
This woman may enjoy the companionship you offer & likes the fact that you both can be friendly together w/out any sexual overtures involved.
Or:
She may see you as a potential mate.
This is a tough call because if you did make a move toward her and she doesn't feel the same about you, then you will have compromised a lovely friendship over it not to mention that work will be entirely painfully awkward.
Just continue your friendship and let the chips fall wherever they may.
Personally as a Female myself, if I felt some spark w/you...then I would want too see you more frequently.
I would also have to proceed w/extreme caution as well considering that we worked together.
Please keep us updated if you guys eventually end up dating!
