The advice nevertheless appears that making use of condoms plus silicone or water based lube could be the way that is best in order to prevent STIs.

Hardly any individuals reported one off or casual anal sex: just 5% of individuals reported they had had a single off intimate encounter involving rectal intercourse over the last thirty days (just last year if a female). In contrast, 56% reported anal sex over the past thirty days (a year ago if a lady) by having a partner that is main.

Just 12percent of individuals hadn’t utilized commercially bought lube at all, but just 32% of individuals had utilized lube each time they had rectal intercourse (the ‘consistent lube users’). One important caveat is neither the sachets of lube provided with free condoms, nor advertisement hoc lubes like hand cream, had been counted in this study: it just concerned lubes purchased on the counter.

There have been differences when considering constant lube users as well as other individuals. Lube users had been almost doubly prone to have HIV should they had been under 35, though perhaps not when they had been older. African Us americans had been not as likely than normal become constant lube users and Hispanics more so. There have been no differences when considering lube users and users that are non the amount of lovers that they had or what number of times that they had anal intercourse.

The study discovered that 9.5% of consistent lube users had an STI versus 2.9percent of inconsistent/non users (three times more). This is statistically significant and these outcomes had been separate of people’s age, race, gender, HIV status, amount of lovers and quantity of intercourse.

What about condom use?

Understanding condom use is problematic, because, while individuals had been inquired about if they had had receptive anal sex and/or utilized lube throughout the last month, these were just expected if they had utilized condoms the last time they’d rectal intercourse. Therefore we cannot say, by way of example, whether those who utilized condoms the final time they had intercourse had more or less lovers, or white girl sex had intercourse pretty much frequently, than those who hadn’t utilized condoms.

However, in univariate analysis (in other words., perhaps perhaps perhaps not using other facets under consideration), condom use at final intercourse wasn’t significantly protective against STIs: 4.6% whom reported condom use last time they’d anal intercourse had an STI in contrast to 5.1per cent of the whom would not report condom use not a difference that is statistically significant. This does not indicate that condoms don’t force away STIs. It might imply that, because condom users had been very likely to utilize lube (44% utilized lube versus 24% of these who didn’t usage condoms), the protective effectation of condoms had been eroded by way of a harmful aftereffect of the lubricant utilized. It might imply that condom users had more sex that is anal but we don’t understand.

What conclusions can we draw about lubes?

The kind of lube didn’t really make a difference. One concept 2 is the fact that water based lubes draw water out from the cells lining the rectum and harm them; silicone based lubes may be safer, as well as oil based lubes for individuals maybe maybe maybe not utilizing condoms. Nonetheless, in this research, although numbers are little because few individuals solely utilized one kind of lube, STIs were more widespread in constant users of silicone lubes in addition to of water based people.

The reason behind these findings is unknown, but has kept prevention employees at a loss about what to express about lubes. It doesn’t show that individuals should stop making use of lubes and also at provide the advice nevertheless appears that making use of condoms plus silicone or water based lube may be the way that is best in order to avoid STIs. No causation was proven: the research could maybe maybe not show just just how long individuals had had STIs and therefore can’t reliably relate them to your times lube ended up being utilized. None the less this research, plus another 3 that revealed most commercially available lubes damage rectal cells to some extent, makes more research into lubricants also to just exactly exactly how individuals make use of them in anal intercourse an urgent concern.
