i have broken my virginity and now I'm feeling tired, weak and nauseous

Hi! Unless you caught an STI or are pregnant (you should go to the doctor and check) you're probably just sick. First of all virginity can mean anything you want but i'm assuming you're talking about breaking your hymen (the tissue near the entrance of the vagina).. breaking the hymen shouldn't cause you to be nauseous or tired. Just pain when you stretch it and maybe soreness.
