Hi , I Have Never Had Sex Or Penetration So

hi , i have never had sex or penetration so i consider my self a virgin. Once i was with my boyfriend and he was touching me with his intimate parts on to my vaginal upper labia. in a second he did hit me by accident but there was no penetration . i bleed for 5 min or less very bright red and felt a sensation of something torn for 2 days . when i check my vaginal area i see that everything is still the same but i dont know if i lost my hymen since i don't see the opening of my virgiana until i cough hardly and it is very small . can you please explain to me scientifically what this means ? thank you
