Ok I know this is bad bad but I’ve seen way worst on here so please try to hear me out 😩

So basically since I’ve been single theres 2 guys I’ve been rotating sex with the last year and a half one is my ex one is a guy who visits occasionally since he moved. last year he (my ex) gave me a STI so I cut him off for awhile somehow he made his way back in 😐 except this time always use condoms! fast forward to this year again I’m single so I never know when I’m gonna have sex one month particular I had sex with them both of them 2 times a piece 😬 guy number one told me I can go get a condom & then proceeded to put it in before I got up granted I could’ve stopped him after but it’s been a while and I just caved 🥴 week or so later my ex and I had a sleepover with a lot of sex we used condoms until the middle of night he put it in unprotected 👎 so that leaves us to a few days ago from today I had to get two needles in my vagina and one in my ass to drain a huge cyst next to the opening 🤬and to get rid of the new STI I was given 😐but here’s the problem I’m mad mostly at myself because I don’t do things like this idk why I got comfortable however I don’t know which one of them I got it from I sent out an anonymous text to guy one because I’m sure he has it now rather he gave it to me or not🙃 but Idk what to do or say to my ex I just know I’m done done especially while I’m detoxing & aching 😤 I do know this....... ☝️ the first time we had sex that month I only had unprotected sex with guy one and didn’t have any symptoms for weeks until after I had unprotected sex W/ my ex then I got all the symptoms within 2 weeks so now I’m thinking it’s him? I don’t want to falsely accuse him because we’ve been getting along so good lately if it wasn’t him then I don’t want him to know 🤦‍♀️🥴
