I am just after some clarification as I have never been in this situation before.

So I'm new to the whole FWB situation, I'm 30(m) she is 24(f) and we are co-workers. She is super hot and I'm just a single dad with two kids.

So our first, second encounter of just "hanging out" turned into takeaway, netflix and then sex with lots of cuddling afterwards. The third and fourth time she invited me over was her cooking me dinner, making out (no sex as it was her time of the month) and spending the night.

We also text each other ever day just chatting, asking how our days were and what we have been up to as we work in different departments.

What has me confused is what I read online. Apparently there is not meant to be much or any emotions/feelings involved with FWB, well that and she occasionally says feelings and men are gross. Also is protection important in this situation, she is on something but should I wear a condom for my own personal sake?
