Irritation after masturbating, I saw a little redness and soreness

Hy,

Yesterday, my gf masturbated me for the first time.I felt so good, didn't felt any pain.Maybe a little bit when she pulled the skin fully back.Today I woke up, and felt irritation in my penis, so I pulled back the skin and saw a little redness and soreness.I put a little cream on it, but I still feel it.Should I go to a doctor, or she was maybe too rough because it was our first time and it will heal itself in a couple days?Thanks.
