Background: Little is known about the frequency and type of commercial lubricants used during anal intercourse (AI) in different countries. Gathering information on lube use patterns and preferences for anal intercourse (AI) facilitates decisions on which commercial lubes to test for rectal safety, and provides crucial information on acceptability of eventual rectal microbicides.
Methods: The International Rectal Microbicide Advocates (IRMA) developed a web-based 25-question survey in English, French, Spanish, Portuguese, German and Turkish posted on www.surveymonkey.com and advertised through a variety of mostly online methods.
Results: The survey ran for 29 weeks, from 2/14/07 - 8/31/07. 8,945 people responded from 107 countries, with 6,273 reporting AI in the past 6 months. The vast majority of respondents were men, but over 900 women responded to the survey. A small percentage of respondents stated a preference for lubes that have flavor(4.4%), colour (2%) or smell (6.6%). Little more than a quarter who had engaged in AI provided reasons why they did not use lube. The rest indicated they didn´t have AI without lube, or didn´t answer. Common reasons given for not using lube: used saliva (over half respondents), lube not available (nearly half), prefer dry sex or used lubricated condoms (approximately one quarter of respondents each). Overall, responses indicate considerably high acceptability of lubes for AI. The study also discovered other substances commonly added to lube (i.e. saliva, vaginal fluids) and the most widely used lubes.
Conclusions: A rectal microbicide that is similar to existing lube products will be acceptable, especially if it has no flavor, color or smell, and is available in both thick and liquid consistencies, and in both a water and silicone base. When testing current lubes for safety, and testing potential rectal microbicides for efficacy , researchers must consider other substances (spit, water, vaginal fluid) being added to the product.
