This may be awkward but... Haha

Have you ever given your man a BJ after he's been inside of you? I did once and I almost gagged because of the taste on him from being inside me ? if that's how I taste idk how he goes down on me. Haha but he might like the flavor?
And I never ask him to go down on me but he still does it anyways!
Like I'm sure he wouldn't want to taste himself but to me his flavor is just normal and I don't mind. 
Anyone ever had a situation like that or wondered if he likes how you taste? Haha or just any opinions on this? :p
