Last week was the first time I've had since since May. It's also the first time having sex since I've given birth to my son (which was 4 months ago). Well, initially the guy inserted me before I was fully wet. His dick was huge. I was fine for the most part and eventually got really wet. We had sex for a long time. We also used a condom. The next day I was in so much pain. I'm assuming I was scratched from not being wet fully when he inserted me, which stings when I urine. But i also have a lot of discharge, mainly yellow. I called my dr and have an appointment scheduled in 2 days but i am in so much pain. I would think i have an std If I hadnt used a condom. Anyone else experience this? It's so much discomfort. Any temporarily relief suggestions until I am seen?

I'm assuming it's a reaction to the condom, it's the only thing that I can think of.
