Closing the condom gap is a public health challenge. Monogamy should not be taken for granted, however. A review of studies in 63 countries for this report finds that many married men have sex with someone other than their spouses. Use outside marriage. This includes both use in extramarital sex and use among the unmarried.
More men report using condoms than women.
Few data are available from Asia. Use with multiple partners. In some countries recent surveys among people with nonregular partners show high levels of condom use.
