Hi girls. Last week u had sex with a new parter. He was bigger than what im used to and it was hurting when we were having sex. Now i feel like i have red marks at the entrance of my vagina and little bumps it burns when i pee. Is this friction? Should i be worried? I havent seen any other changes besides the bumps,redness and burning. Is there a remedy? Is it something i should go to the doctors for? I am worried since it is a new partner
