Are boys really that lacking in self-control?

Are guys really that lacking in self-control? Last night, after having barbecue with an ordinary friend of mine and playing together, it was already very late and there was no way to get home by car, so we decided to find a hotel. I thought since we aren't dating, it was no big deal. He is also a pretty good person, quite well-mannered. Maybe I was too naive, but I didn't expect him to start doing that. I found it very strange and, after struggling for a long time, I still didn't agree. Are guys really that lacking in self-control? Even someone who is usually well-mannered can be like this? Actually, my relationship with him is pretty average; we've only met a few times, and he treated me to a few meals. Last night, after eating together, we went to stroll a bit and sing KTV. Maybe we had too much fun, and when we came out, we realized there was no bus home. And because it was too far to get home, the taxi would cost over a hundred yuan, which made me a bit hesitant. Seeing my dilemma, my friend suggested that we rent a hotel room to rest and go home in the morning. I looked at his sincere expression, knowing he is generally a good person and considered relatively well-mannered among his peers, so I nodded and agreed. To save money, we rented a single room. After showering, we slept together. I slept on one side, and he on the other. After lying down for a while, he came over and asked me to snuggle closer, to talk while sleeping on one side. Since I speak softly, he couldn't hear clearly, so I agreed and lay on his arm while talking. Later, he simply hugged me and wanted to do that kind of thing, saying that nowadays everyone is open-minded, and it wouldn't be a big deal. He even said he brought a condom and could make it very pleasurable, which terrified me. I struggled for a long time but still didn't agree because I didn't feel ready. He really is quite decent; seeing that I didn't agree, he gave up and continued to talk with me, letting me rest my head on his arm. Now I am very surprised. Are all guys really that lacking in self-control? Why does he think about that kind of thing as soon as we book a room? Did I misjudge him? Why is he so creepy? He's not usually like this at all, even though I also got aroused!
