I don't believe at any time in history there should have been shaming of those that chose to go natural when it came to anal sex. Shaming doesn't work, however education and harm reduction does. Before PrEP and TasP (Treatment as Prevention) however it was highly risky to engage in passive anal intercourse without a condom, unless perhaps you had discovered you were amongst the small group that appear to be genetically resistant to HIV. The stigma is lessened because the risk is lessened. Natural anal sex when you're on PrEP is no more irresponsible than natural oral sex for those not on PrEP, so I really hope the shaming and name calling can be finally and completely put to rest.
BTW, if I haven't made it clear before, I've been on PrEP for 5 years and ABSOLUTELY prefer the intimacy and connection that comes with natural, skin-to-skin sex, however my client's comfort level is priority over my pleasure, so I'm happy to wrap it up, if that's what's neccessary to keep them comfortable.
