Hi. Finally Me and ny girlfriend have decided to have sex. But we have problem. My girlfriend is a virgin and because of the situation in my country she cannot decide for herself to lose virginity only when shes married. Fortunately she let me to have sex by her vagina because we have heard that if penis does not go deep it will keep the viriginity . NOW WE dont know how much of the penis is allowed to enter without losing virginity ???? Please help me.
