Lots of research into human sexuality including orgasm, penile enlargement\/implants, hormone effects, clitoris stimulation, and etc. Most of them are overly detailed and researched. Author’s comments in the footnotes are often full of tongue-and-cheek to draw quick laughs. It’s good to be not too serious about this topic. I’m not sure I’ve gotten much except the following: human sexuality is a lot more complicated than our primate relatives, the science behind impotence and the functions of erectile penis, orgasm and the G-spot, orgasms for paraplegic seems gives us clues how it’s connected to the brain, sexuality experiments in Islamic countries could be a risky undertaking and even in a free country like USA it could be problematic, and etc. <\/p>\n
