This is an interesting read from the point of view that your points about the stigma of STIs leading to those suffering feel unable to seek treatment is tragically true. Someone very dear and close to me in my family recently died as a result of complications due to contracting HIV. They had the infection for 8 years but kept it to themselves until they were in hospital 2 months before their death. They didn’t seek treatment until 2 years before death (by being put in a position where they had to as a result of a different medical condition) by which time it was too late. The stigma surrounding it was undoubtedly the reason why they could not feel able to seek treatment as well as support from their family, who would have loved and supported them wholeheartedly. Had they been able to be open about it chances are they would still be here today living a normal life for many years. The whole thing is a fucking tragic travesty and is the saddest thing I’ve ever known.
