Warming liquid

Has anyone ever had a funky odor down there the next day after sexual intercourse?

It’s only happened to me like 2-3 times and each time it’s happened ive used the KY Jelly warming liquid.

Yesterday I had sex & I used at first the durex 2 in 1 massage and play lubricant and after an hour or so we decided to use the warming liquid.

I don’t know if the liquid has anything to do with my PH or something.

Im 100% clean, i check my self all the time & have no stds or anything of the sort. I’m just curious as to why it happens and why it happens when I use that product.

TIA
