I can't answer your question either.
Keep in mind that a man who seems effeminate is not necessarily a gay man, and a gay man is not necessarily effeminate. Those are stereotypes, and you should meet my friend E's husband, who is one of the most manly men I've ever met.
I don't know when you were in high school, but I attended high school from 1994-98, and we read all three of those books as part of the standard curriculum (we also read To Kill a Mockingbird in 8th grade). For a white suburban girl (and at that point didn't realize I was gay), I found them enlightening.
I also read Beowulf, though in a modern English translation, in an honors English class when I was a senior. I found the first part, climaxing in the epic battle with Grendel, to be very exciting. However, like you, I had a hard time getting through the rest of it. Years later, I read a new translation by Irish poet Seamus Heaney. I highly recommend it.
