big identity problems with sex

alex • lover of most things fried chicken related
so heres the thing, 
      im 15 and ive had some sexual experiences, a couple w a girl and one w a guy. all were exceptionally terrible. girl couldnt get me off. like. ever. and guy made my first experience with a dick exceptionally forceful, rough, scary, and outright painful. ive never enjoyed sex though i have sexual feelings and enjoy making out and sex in theory. everything thats happened before has felt so wrong and/or painful and im almost at a giving up state. im now scared to have sex with guys and unexcited to have sex with girls. i think a lot that the problem lies in my own nature but looking back those two partners were just truly terrible???? i want to know how to have healthy sexual and romantic relationships and how to find someone (guys especially) who wont use me sexually and who wont not care about how much what hes doing is hurting me? any advice would be greatly appreciated❤️❤️❤️❤️
