Is this a red flag situation?

This guy that works with me we started off as friends with benefits but were really good friends and we stop doing that because he went back to his ex and got married and I just been feeling like off ever since he told me but he really cares for me today he asked me if i needed some D*** and I was like no and he knew I was lying but didn’t say anything and he said if I go to the bathroom u won’t follow and I was thinking I would but I know my place and I said no I wouldn’t do that because your married and he was like I wouldn’t of went and I knew he was lying but when he said he wouldn’t of went to the bathroom he sounded a bit disappointed of my answer and he also said some girls when there acting weird and stuff they just need some D*** and I was so confused
