So im 13 and i lost my v card at the begining of this year but anyway i had sex last month and ive been kinda paranoid but i asked the person i did it with if he was sure that nothing got inside and he said that nothing did but im still paranoid but ill start to think that im sure everything will be fine but i keep thinking about it. I just need some advice/ reasurence.(sorry i might have spelled that wrong)
