What's the 'alternative forms of sexuality'?
Solution 1:
The Beats included figures like Allen Ginsberg, Jack Kerouac, and Lawrence Ferlinghetti. These were mainly poets and writers, with some elements of performance art seen among their collected works. "Alternative sexuality" in the quote above refers to non-hetereosexuality. This was not a defining characteristic of the Beats as a group, but some members were fairly forward about it at a time when doing so was highly unusual.
