How is this possible?

In Mexico, it's estimated that at least two people are raped every hour. I didn't know this statistic until recently. When I was abused, I minimized what had happened to me. I thought, "There are girls who are raped and tortured, they die, or they're never found again, so why would my case matter? I'm a man, how can anyone believe that a man suffered sexual abuse?" You see, I'm 22 years old. It was just a regular day. I had recently broken up with a partner, and a "friend" from high school, who was once my ex, messaged me. She replied to one of my Instagram stories, and we started talking. It had been a long time since I'd seen her. She said, "What do you think about meeting up on Monday?" I agreed and said, "Sure, let's go for coffee." She lives alone, so the idea of going to her place and eating didn't seem bad to me, like two mature adults. She said, "Let's go to a coffee shop," and I said, "Okay." We were going to be at the coffee shop for two hours because she had to leave for an appointment afterward, and I had an errand to run. Halfway through coffee, her mother called and canceled her appointment, so she didn't have to leave. After that, we went to a nearby bar, had a couple of drinks, and played a game of pool. While we were playing, she seduced me and kissed me, which at first didn't seem unpleasant. After a while, we decided to go to her place. We arrived, and obviously, the idea was to kiss, make out, and leave. I didn't have condoms, and I didn't want to go any further because I had doubts. I still didn't know if I wanted to get back with my ex, so I was holding back or if I wanted to go further. We got to her room and started kissing, rubbing, and a little touching. We started to We started undressing, and I decided not to take my pants off. She insisted, and I awkwardly said, "Fine." I stayed in my underwear, and we continued kissing. After that, she climbed on top of me. This girl wasn't heavier than me, but she was still heavy. When she got on top, I felt something strange: she wasn't on my pelvis but on my stomach. She kept kissing me, and at some point, I ran out of breath. I could still breathe, but I felt too weak to move her. She said, "I want you to put it in," to which I replied, "No, I don't have any condoms, and honestly, I'd rather not do it that way." She told me she had the implant for health reasons, to prevent pregnancy. I immediately said, "It doesn't matter. Pregnancy isn't the only thing I'm worried about. I don't have any condoms, maybe another day." She didn't say anything and kept kissing me. After a while, she lowered her hand, pulled out my penis, and I tried to remove her hands. I said, "Stop, I don't want to." She didn't seem to hear what I said. "Wait, you're not going to like it. I recently had an infection, and it's better this way." So, she said, "Oh yeah, an infection?" I didn't know what to say at first, and she said, "That's a lie." She put it in, sat down completely, and after a few seconds, I ejaculated. Uncomfortably, I said, "Okay, I'm done, I can't do any more." Despite that, she stayed sitting on top of me, in the exact same position. I said, "Okay, we're finished, please move." She said no, that it had been too quick and that she wasn't satisfied yet. I said maybe another day. She noticed my discomfort and asked, "What's wrong?" I said, "I have a lot on my mind. Can you move?" She still ignored me and said, "I can't get pregnant, and if you're worried, it's been a year since I've been with anyone. I don't have anything." I said, "That's not it." Out of ideas, I said, "I'm running out of air." She shifted a little to the side, and when I could breathe again, I was able to move her. I started to get dressed, and she, still naked, grabbed my clothes, hugged them, and didn't want to give them to me. She started saying, "So you're going to abandon me?" You'll leave me here naked, come on, let me clean you with my mouth, wait a bit and let's continue, or sleep here. I told her it was late, that I had to go home and couldn't stay. Still holding my clothes in her arms and refusing to give them to me, I said, "Fine, I'll come back another day." She said, "Okay, but you'll stay that day." I said yes, that it was no problem. Only then did she let go of my clothes and give them to me. I got dressed and left, got in a taxi, and started texting my best friend. At that moment, I felt stupid and had never felt so vulnerable. I kept blaming myself and telling myself over and over, "If you hadn't gone, everything would be fine." I talked to my best friend and my therapist, and later to a support group, and they all said the same thing: it was rape. I stopped crying and started telling myself, "You can't be that stupid." I started minimizing it, and as I said at the beginning, I kept repeating to myself, "There are girls who don't come back, they're drugged, raped, and tortured. They're never..." We met, you went to her house, you drank with her, you agreed to make out, how can you call that abuse? Yet I still feel guilty, I feel empty, alone, and very scared—scared of an STD, scared to tell anyone, and even scared to admit it. I can't help but think that maybe I was the one to blame, that I shouldn't be complaining, and that if I tell anyone, they'll just say, "Why are you complaining about it?"
