This 19-year old should only be so lucky.

Hey kids, its Hump Day (otherwise known as Wednesday to normal people) so here's a sex fact!

18-29 year olds have sex an average of 112 times per year, 30-39 year olds an average of 86 times per year, and 40-49 year olds an average of 69 times per year. (Source: the Kinsey Institute FAQ)

edit: I'd also be curious to know whether this statistic dealt with heterosexual PIV sex exclusively.. it doesn't say. Hmm.
