Discomfort After The First Intercourse?

Hi, I'm 15 and recently my friend and I decided to have some fun. There was no penetration of a penis into the vagina, but there was penetration with your fingers. All this activity lasted about 2 and a half hours and he was quite rude. I forgot to mention I'm a virgin. Tee, when I read that the virgin zipper can break, and with the penetration only on my fingers, I keep to mention that it is possible that he also tore it. There was no blood, but there was a pain. Then began terrible discomfort of the kind of burning at the entrance to the vagina and between the vagina and the anus (I hope you understand which part I'm talking about). The area is slightly red and I had a slight brownish current. After urination there was a little burning, but not scary. When I broke in, I wasn't particularly excited, and I think that might be the reason. Maybe he frothed me or something. I want to ask if I should worry, is it normal, should I visit a gynecologist, etc. Thanks for the answers in advance!
