I am very confused as to why I feel so much pain after sex. Usually the pain is felt around the vagina on the labia and near the anus. This pain feels like intense burning/inflamation. I also sometimes experience some blood. This is not because during sex the area is not lubricated, it is. Also this intense pain only happens when seminal fluid touches the labia and urination. After about an hour the pain stops. I would prefer to continue having natural sex (without condoms) but the pain shortly afterwards ruins the entire experience, please help.
