Why you should be sexting

Sexting is now a normal part of human relationships, according to a massive new study of sex and tech -- 74 percent of Americans say they exchange saucy electronic messages with their lovers. "Sexting may be becoming a new, but typical, step in a sexual or romantic relationship," said Amanda Gesselman, a research scientist at the Kinsey Institute, which released its annual International Sex Survey this week. The researchers surveyed more than 140,000 people from 198 countries about the role of tech in their sex lives, and found Americans are some of the most prolific sexters on the planet -- second only to South Africans. Japanese and South Korean adults are the least likely to trade racy missives. Worldwide, 67 percent of adults said they've sexted -- a staggering increase from just five years ago, when only 21 percent said they engaged in the practice.
