don’t know what to do..

so about 2 weeks ago i used my friends vibrator. i cleaned it with warm water and dish soap before i used it and then i just kept it. i’m scared that i didn’t clean it well enough but i also know i tend to get super paranoid when it comes to stds because i got chlamydia when i lost my v card. i’ve had sex with my boyfriend since, and there’s no pain during sex or when i pee or anything. it just feels like a strain in the right side of my groin sometimes and yesterday my vag was hurting on the inside of the right side so i don’t know what the fuck to do. i can’t tell my boyfriend, he’ll be like what the fuck. same thing with my mom, and if i go get tested, she’ll see it because she has the code to my records at my gyno and also bc of insurance. am i being paranoid? she also hasn’t used it in a while and i don’t think stds can live outside of a person for too long, right?
