Hello, I’m Tatyana im 18 year old I had sex

Patient: Hello, I’m Tatyana im 18 year old. I had sex on April 24 without a condom, it only lasted for five mins or less. We gave each other oral and he also sticked his finger inside of me. When I got home i peed and washed up, the next day we had sex again but I told him to use a condom which he did at first, at the end I noticed it wasn on he Didn tell me so we no longer talking. I asked him if he has any type of std or hiv he said no, but it took him a day to answer Ik he read my message beacause it says read. This never happen to me before I always use condoms and I am scared since he took a day to answer. What should I do ? Do u believe he has something just doesn’t want me to know ?
