Prevent STD

(Not seeking advice just a true story)So , me and this boy we had been dating on & off for 2 years I lost my virginity to him , then finally we parted ways and decided to just "talk" of course with benefits. Well he had been trying to get back together & of course I wasn't having it because I knew the type of person he was , but we were still having sex (unprotected) only because he was the only person I was having sex with and thought he was doing the same. Well unfortunately He wasn't, some girl messaged me on social media telling me she had sex with him & that he was infected with an STD(it was curable) sooo I decided to go get checked turns out she wasn't lying he infected me as well. LISTEN LADIES IF YOU AND YOUR PARTNER ARE NOT TOGETHER PLEASE REFRAIN FROM HAVING SEX WITH THEM. Even if it's protected just spare yourself the problems anything could happen. Please be safe. & watch who you give it up too
