Solo, the consent premise is simply yours: you can slow down, stop, or change your mind at any moment, for any reason, with no one to answer to. That freedom is the whole point of practicing here.
This is an awareness practice, not a treatment. Nothing here promises to fix premature ejaculation, erectile difficulty, or delayed orgasm — the techniques it borrows have limited evidence even in their original clinical context. If a sexual difficulty keeps weighing on you or a relationship, doctors and sex therapists treat these concerns routinely; that's the right door, not a downgrade.
On pornography specifically, both things are true and this article takes neither side: compulsive sexual behavior disorder is a recognized diagnosis in the ICD-11 — real, distressing loss of control exists, including in people with no moral objection to porn — and the guidelines are equally clear that feeling morally conflicted about porn is not, by itself, a disorder. If your use feels genuinely out of control or distressing, take that seriously in its own right; a professional can help you tell which of the two you're dealing with.
If slowing down repeatedly triggers distress, numbness, or a sense of leaving your body — especially with a history of unwanted sexual experiences — that's a signal to stop the practice and bring in professional support. It's not a failure of the experiment — and you're not the only one it happens to.
Physical signals are hard stops: pain, chafing, numbness. Lubricant and a gentler grip solve most friction problems; persistent pain or numbness is a medical question. And a note on the evidence: the studies behind this piece mostly sampled heterosexual men, or didn't record orientation. The observations are drawn from those samples — your experience is the final test.
