Discussion thread missing? Can anyone help find?

I recall reading in this sub-forum some months ago a comment about clinical trials of a rectally administered pre-exposure prophylaxis (PrEP) for HIV. The medication was packaged as a gel or suppository - can't remember which - to be used before anal sex.

The clinical trials were described, and they sounded like they had been devised by one of the med-fet/klismophile crowd here at Zity. The volunteer subjects were gay or bi males between 18 and 45. They were first administered enemas, and after voiding were given the rectal medication, then subjected to a period of vigorous penetration with dildoes. Afterwards there was assessment of how much of the drug had been absorbed transrectally. I believe sigmoidoscopies may have been done as a part of the assessment. A link to the research paper was provided, and it confirmed the description summarizing it here.

Can anyone find this thread and post a link to it? I'm not interested in it for technical or personal reasons, just for its having described an unusual and erotically entertaining true-life occurrence.

@ekim2653 I think this might be the thread you're looking for.

Thanks - that's it!

That seems to be a crazy study. Not a volunteer. Gives me the willys. 🤮
