To Use a Rectal Microbicide, First Insert the Applicator: Gel and Applicator Satisfaction Among Young Men Who Have Sex With Men.

Abstract

We examined how experiences with a rectal placebo gel and applicator used with receptive anal intercourse (RAI) related to young men who have sex with men's (YMSM) likelihood of using a rectal microbicide gel and applicator in the future. An ethnically diverse sample of 95 YMSM (aged 18 to 30 years) were asked to insert hydroxyethylcellulose (HEC) placebo gel rectally before RAI during 12 weeks and report the product's acceptability (i.e., satisfaction with applicator and gel, respectively; perceived gel side effects; and sexual satisfaction when gel was used) and likelihood of future microbicide use. Main and interaction effects predicting future use intentions were tested using linear regression. We found a positive association between future use intentions and applicator satisfaction (b = .33, p < .001). In a subsequent interaction effects model, we found that greater gel satisfaction was associated with increased future use intentions; however, the strength of this relationship was magnified when YMSM reported greatest satisfaction with the rectal applicator. Applicator satisfaction may be a salient factor in YMSM's decision-making to use a rectal microbicide in the future. Although the importance of developing a satisfactory rectal microbicide gel for YMSM is undeniable for its future use, our results also emphasize the importance of developing strategies that increase YMSM's comfort and skill when using a rectal applicator. Future research examining how to optimize the design, properties, and characteristics of a rectal applicator as a strategy to promote greater satisfaction and use among YMSM is merited.
