I feel embarrassed even writing this but last night my dp started to go "down" on me then stopped. I asked him if everything was okay and he just said "yes" then starting having inter course on top. I felt something was wrong and couldn't enjoy sex so just said I felt a bit tired and could we stop.
This morning I asked about the oral sex because he doesn't usually just stop and he said well yes, I'll be honest and say I started but could taste "wee" so stopped 

I said it might be because I came off my period a couple of days ago it takes a few days to get to normal, to which he agreed and said not to worry and tried to reassure me it would be my post period phase.
I feel mortified.
This has never happened and I now feel paranoid about the "taste" downstairs. If he does oral again I am going to constantly thinking does it taste ok, is he enjoying it etc.
I shower daily and look after myself.
Has anyone ever had this?
