Painful sex.. New at this, I need help (SUPER PERSONAL)?

girl that flap of skin is called a hymen. it blocks or partially blocks the vaginal orfice (hole that you have sex with) in virgins. so you tore it when you lost your virginity. it also hurts because your vagina (that is the part that is inside of you) is a muscle , and it you hurts when you stretch a muscle like that so suddenly. plus, (this is just my opinion) you should probably not be having sex if you don`t have basic sex education. like do you even know what std stands for or how you get pregnant?......but anyway...that is just an opinion. so there`s your answer.
