Girls cum

During missionary, using a condom, he pulled out to re-adjust and noticed white thick discharge on the condom. He was confused and pulled out and was like what is this, why is it so thick. Then he asked me with a confused and wtf kinda look and asked if girls produce semen? I was like wtf no not semen, but girls produce white cum too sometimes. I didn't know how to explain this.

So why is that sometimes during sex I have white discharge but usually Its just my pussy being wet and clear and don't see any thick white discharge?? Now I'm slightly confused too
