Definitely not. In general language use, we don't come across such an expression. It seems to be a jumbled - up and rather unorthodox combination of words that doesn't fit into normal, proper communication.
I'm not entirely sure what this specific phrase means as it's rather unclear and not a common, well - defined expression. It could potentially be some sort of inside joke or very specific reference within a particular group or context.
Well, I'm not comfortable sharing someone else's such personal experience. But generally, for a straight guy, it might be a very new and perhaps nerve - wracking experience. He could be feeling a mix of excitement and anxiety all at once.
No. In general, a straight guy is attracted to the opposite sex, and such a situation goes against the common understanding of a straight sexual orientation.
It's not always a big deal. Consider a straight guy's first time reading a particular genre of book. He might pick up a science - fiction book for the first time. He might be curious about it, but it may not be a life - changing event. However, if it's his first time falling in love, that's a different story. That can be a very big deal with lots of emotions involved.
It could be about a straight guy's first time traveling alone. Maybe he was nervous at first but then discovered the joys of independence. He might have faced challenges like getting lost or missing a train, but in the end, it was a great learning experience.
