<human>: Can you summarize the given text in a few sentences?

Ill start. So I was in 11th grade, and I had a little presentation on I think was something history related. I wasn't exactly ready and decided not to volunteer to go first. Well, no one volunteered and I was called on. I was wearing some loose basketball shorts, and I had the biggest hard on I've ever had. My scumbag brain decided to think about the girl next to me. So I walked up, and slowly turned around thinking it would go away, and started with my presentation. Some douche bag yells "nice boner!" Holy shit I almost died of embarrassment, my face was beyond fire-truck red and then someone decided to comment on how red I was which of course, made it worse. I had one of those 'cool' teachers who chuckled real quickly and told the class to stop and I continued to stay frozen. He said he would call on me the next day to do it. I was scared to go to that class, let alone anywhere in the entire school for the rest of the year, I roughed it out but was usually constantly fucked with.
<bot>: Got a boner in front of my class right before I started a presentation, got embarrassed, made fun of for the rest of the year.
