what was it

So me and my SO was having sex today and when we were done he had discharge from me being aroused on his penis. It was white. Is this bad? He said he came in me and kept going so that could have been it also, but then again I know us ladies sometimes get discharge on the penis and they think it’s cum lol. But is this cause for concern? I heard ejaculate (Not really ejaculate I know) from a women is suppose to be clear. But I’ve read tons of ladies and even saw porn videos when white stuff appeared on the penis from arousal or orgasm. he read also that it’s suppose to be clear.. I’m wondering if I have some type of infection. I was tested for STDs and negative. So maybe yeast or something?
