So I got this woman at work who is on and off with her boyfriend. She will openly flirt with me at work and has tried steering our conversations on a sexual basis. Recently she asked me how many women I have been with, I replied with a "I lost count at 200" trying to be playful. She asks me how things are going with girls I have gone on dates with. I reply to her by saying "Don't worry about it". Now how should I go about this one and should I sleep with her. If yes how should I engage the next step?
