Sore coochie

So I had sex without a condom with a new partner 2 days ago, his penis wasn’t huge but it was enough to do the job🤪🤪 anyway, my coochie still hurts on the outside right around the hole and sitting down is painful. I had a urine test for something completely unrelated today and it came back with blood in my urine and I’m worried something could be wrong. I’ve also had milky discharge. I’m no stranger to getting big dick but this feels different, anyone else experienced anything like this before??🙏🏼
