There were a few negatives for me. I do think that parts of the near endless sex could have been removed - not in the interests of toning it down, at all, but merely because they served no purpose to telling his story. After a while it became repetitive and boring. I think I've mentioned this before but writing about sex should never come across as dull unless that is completely 100% the intended effect, which I'm pretty sure is the opposite of what's being described here. Also, though interesting to know about his "relationship" with Flea's sister, I think a little more tact around his oldest friend could have been exercised. Sounds like Flea was pretty pissed off about that ending up in the book. Memoirs and autobiographies do to automatically have to include those kinds of details about other people's families!
Still, fascinating read. I can see why the book is so popular.
