I’m very scared i could have contracted HIV

Im sorry the details of this story are going to be a little bit graphic, but really I haven’t been sleeping well for more than month now because I have been so fixated on this. I’ll start off by talking about the person I have slept with last year (November 2023 to January 2024) that is making me worried sick. He’s a heterosexual 21 year old male who at the time was my boyfriend, and had told me he only had one girlfriend before me. We had a few sexual encounters, in which we either practiced protected sex or oral, where I unfortunately swallowed almost every time. I think I did oral about 4/5 times, last time being around the middle of January last year, first time being December I think. January 18th 2024 he. cheats on me in the United States (I live in Italy) with a girl from Umiami he had already had sex with the year before. He confesses to me that before me, he had actually had sex with 26 other women, all our age, all heterosexual, from his college in Wyoming and when he went to study abroad in Barcelona. I was worried sick… I asked him about his usual way of having sex and he told me that they would practice oral sec on him and then he would have protected sex with them (he never had full unprotected intercourse where he ejaculated in a woman and he never did anal). However, I am not sure I can trust him. I waited as much as I could, being humiliated and not able to tell anyone, and march 17th 2024 I took an Oraquick rapid test which turns out negative. I never had any other sexually transmitted infections and neither did he. I never developed symptoms after the various exposures. The fear came back and I am distraught. I can’t sleep and eat, I have become alienated from my family. Please let me know what I could do, at the moment I can’t take another test because I can’t talk with my family about it and I have no possibility of accessing it in private. should I be very worried?
