<human>: Give me the gist of the text in a nutshell

Moments ago in one of my Sociology classes:

To start, I am a fairly facetious person and my classmates and professor know this. The guest speaker, however, does not know this. The guest speaker is part of the LGBTQ community and at the end of his story, he opened it up for some Q&A. Well, I was curious as to how his hall responded to a gay dude living among them after he came out in college, because he went to a small Christian college. I thought I would be funny and I asked, "Given that all gay guys come onto every single straight guy they encounter, how was the reception from your hall mates?" The class gave a light chuckle and my professor cracked a smile. The guest speaker turned red in the face. He exclaimed, "Whoa!" and went on to give me about a ten minute chewing on how that stereotype is far overplayed and there is no reason to further that stereotype. My professor tried to help my cause by pointing out that I was attempting to use it in a pejorative manner, but he was too far gone. I feel like such a douche..
<bot>: I tried to be funny and ending up pissing a guest speaker off, made myself look like an ignorant jackass, and got a nice little lecture out of it.
