↑ "Most of the time, condoms work well. However, condoms are more likely to break during anal sex than during vaginal sex. Thus, even with a condom, anal sex can be risky. A person should use generous amounts of water-based lubricant in addition to the condom to reduce the chances of the condom breaking." Center for Disease Control; "Can I get HIV from anal sex?"

↑ " There is a common misconception that anal sex is practised almost exclusively by gay men. This is certainly not the case. It is thought that an estimated one third of gay couples do not include anal intercourse in their lovemaking. About one third of heterosexual couples try it from time to time. It is thought that about 10 per cent of heterosexual couples have anal intercourse as a regular feature of their lovemaking. In absolute numbers, it is hypothesized that more heterosexual couples have anal sex than homosexual couples.
