So sorry if this is TMI, but me and my SO were having sex the other day and things were getting really hot. He was going down on me for a while and then he stopped and started doing me for a bit and then stopped and brought his dick up for me to give him head.

When i put it in my mouth I had an overwhelming taste of acidic, bitter, sour and had to stop going down on him.

We continued having sex and everything ended well.

I asked him if I tasted bad while he was going down on me the next morning and he said not at all. There was no smell or bad taste and if there was he would have stopped. He also said he doesn't stick his tongue deep inside...

I am a clean person, i clean myself everyday, literally. I never douche. Never stick soap up there, just clean the outside and "lips".

What could be causing this taste? Ive tried googling and some say it could be my diet. I dont eat that bad, maybe too much meat and not enough veggies? Idk. I cant think of what it could be. I don't have gross discharge or a smell. It was just the taste...

Any suggestions on what to do? I am embarrassed by it.

TIA
