A UTI is a urinary tract infection. Women do not pee from the same hole as you penetrate or then cum from. So a UTI shouldn't cause unusual vaginal discharge.
I personally have never had a yeast infection, nor do I have a problem with odder or discharge. I don't understand how women can have a problem down there and not know it, let alone not do anything about it.
Also. women do come, and it can have color too it, but would be a different color and constancy then that of an infection or something.
What I can tell you, is a vagina is very sensitive, it can have allergic reaction to certain types of condoms, or lubricant. That can cause an odder or unusual discharge. I have no problem oversharing here, and letting you men know that a certain lube Steve likes, we cannot use for sex because my vag is allergic to it. It is always best to use either no lube, or a water based or ph balanced lube.
You're welcome.
P.s. You should not be licking chocolate or whipped cream from your local grocery store, that alone can introduce the wrong kind of bacteria and cause an infection, sex shops and other toy providers make special products that are safe to use on the female and male body.
