Suggest a book about sexuality in eastern philosophy.

I am actively deconstructing my Western conservative religious upbringing as it pertains to sex and sexuality and seeking books that address sex and sexuality from other perspectives. I'm particularly interested in books that destigmatize or celebrate masculine sexuality. My past exposure to Eastern philosophy is limited to books like Zen and the Art of Motorcycle Maintenance, and The Tao of Pooh, so I have a very rudimentary base. Preference for non fiction, short stories, and approachable allegories.
