Why are men disgusting?

I went to a get together and saw a guy I found attractive. When I went to the bathroom and came out he was waiting to talk to me. We sat on the couch and we were talking a bit. We were getting to know each other and flirting and then he asks if I can suck his d in the car. I was soooo flabbergasted and disgusted. I immediately thought he was ugly. I wasn’t even flirting excessively either it was mutual and he started it. I’m just disgusted a man could see me in that light. I’m not a whore so I immediately got up and left and told him off. I’m disgusted honestly and don’t want to flirt with any guy ever again. I don’t know if maybe it’s cause I was flirting back? But it wasn’t sexual. Should women just not flirt nowadays?
