Sketchy (mostly wrong) theories I won't tell people about.

• More girls in their late 30s like rough sex because it's a coping mechanism for non-committal boys (or maybe they're just more honest) 
• Raised moles mean you're a bit of a sexual deviate.
• Pretty much everyone with a digital camera has nude photos of themselves.
• That girls on a backpacking holiday are greater conquistadors than boys doing the same thing.
• That eastern European girls are mostly a bit crazy.
• Fat girls like sex more, and not because they're desperate.
• That the meekness of Asian girls is too often a façade and should be dispensed with.
• That American girls really do give the best head (blowjobs 101?)
• That Cosmo's 'Hot Sex Tips' really do bore pretty much everyone.
• Brazilians are obnoxious (never trust someone that takes a drum to the beach)
