Cross-national research on sexual attitudes in industrialized nations reveals that normative standards differ across the world. For example, several studies have shown that Scandinavian students are more tolerant of premarital sex than are U.S. students. A study of 37 countries reported that non-Western societies—like China, Iran, and India—valued chastity highly in a potential mate, while Western European countries—such as France, the Netherlands, and Sweden—placed little value on prior sexual experiences.
Even among Western cultures, attitudes can differ. For example, according to a 33,590-person survey across 24 countries, 89 percent of Swedes responded that there is nothing wrong with premarital sex, while only 42 percent of Irish responded this way. From the same study, 93 percent of Filipinos responded that sex before age 16 is always wrong or almost always wrong, while only 75 percent of Russians responded this way. Sexual attitudes can also vary within a country. For instance, 45 percent of Spaniards responded that homosexuality is always wrong, while 42 percent responded that it is never wrong; only 13 percent responded somewhere in the middle.
