You see, not all people of assorted ages are into, or wanting sex. For all sorts of reasons. So it's perfectly practical and informative to mention one's desire if possibly seeking a partner. Matching up in that area is rather important - yes ?

Sex is a natural biological process. Hiding it or pretending it doesn't exist is not the way to teach future generations what it is, the pros and cons, etc. We are biological creatures -- even religions agree -- they call their herds flocks -- we are not birds. The Puritan ethic that permeates our culture is sad.
