Report on sex-related body mods

[tin_foil_hat]

I'm doing a very brief report on body modifications for my sexuality class.

I was wondering if anyone would have anything of use: scientific names, academic writing on the subject (positive or negative), any procedures that relate to sex (whether it just be aesthetically or physically), any of your own experiences if you like, anything on the culture around body mods and sex would be GREAT.

Oh, and any links to pictures. I have lost my own bookmarks :(

Thanks everyone - Imma edukatin' the ppl!
