It’s the joy of sext!

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.

“This increase, and this large of a proportion of respondents suggest that incorporating tech into our private lives may be becoming normal,” Gesselman said.

An old-school text message is still the most common way for people over 18 to transmit their salacious thoughts, with 65 percent of Americans saying they’ve sent sexy SMSes, while only 38 percent used Snapchat.

The study also revealed that a third of Americans have used an app like Tinder to find a date or get laid — but more say they’re looking for a relationship than a one-night stand.

Thirty-six percent said they used apps to find long- or short-term relationship, while only 20 percent were seeking to satisfy their carnal desires.

Swedes are the most plugged-in when it comes to online dating, with 46 percent saying they’ve used a dating app, while Russians are Luddite lovers, with only 3 percent reporting that they’ve used an app for a hookup.
