Do you remember your first kiss?

Scientists have claimed that most of us can recall 90% of the details of the experience-a memory more vivid than losing their virginity.

In a book, The Science of Kissing: What Our Lips Are Telling Us, scientist Sheril Kirshenbaum writes that men see kissing "as a means to an end" and possibly with a "view to swapping other bodily fluids later".

Women try to "extricate the significance of a relationship based on a single kiss and often that leads to miscommunication."
