Blow job talk

I've just recently started liking to give blow jobs to my man. I've never liked the taste of Cum or sucking none of it I used to gag at the thought. But for some reason my man tastes amazing and I'm now addicted to doing it so addicted that when he has to Cum I let him do it in my mouth and I swallow it and it turns me on so much. He recently just told me he wants me to spit on his dick like physically spit on it and he wants to see my spit dripping from my mouth. Does anyone else go through this? has any of your guys asked you to do this?
