Tight Dry Foreskin, Several Cuts Along Foreskin, Minor Swelling

My girlfriend goes to school in California so for spring break we met up. We had copious amounts of sex the first few nights but no pain. Then one day mid day I felt a weird stinging sensation under my foreskin (I am not circumcised) but thought it was nothing and ignored it ( Maybe relevant? ). Then the following days sex became pretty painful and one morning I woke up and it was very hard to pull the foreskin down at first because of how painful it was, and there was a white flaky band around that part of my foreskin (I assume dead skin). I got up to go take a shower and there was a large amount of Smegma underneath which is a pretty rare occurence for me. After further examination I noticed small cuts all pretty close in proximity in a band around my foreskin. I've been thoroughly cleaning it twice a day with soap and water but to no avail the situation has worsened.

No idea if it was the rough sex and lack of care the first two or three days she was here ? Or maybe a fungal infection ? I just don't want to apply the wrong thing and make whatever situation I have worse.
Thanks in advance anyone who answers.
