Sex with new boyfriend and I have a yeast infection

I am pretty sure it's the beginning of a yeast infection. Something feels off in my coochie and I looked there was only a tiny amount of discharge. I'm gonna see how it feels as the night goes but I think it will be more obvious tomorrow that it's a yeast infection. I told him I think it's cause like we washed our hands but not right before we did it maybe 20ish mins before and we were in the car, touched our phones etc. It's just more annoying than anything
