I remember the week I took it, it genuinely felt like my brain was physically slanted in my brain slightly. Dick can still get hard but when I jack off there's almost no pleasure at all. I use other drugs as well so it's hard to say but I remember brainfog as well.
I will never forget the moment I woke up though the day after taking it. I went in with a positive attitude, completely bought into the whole "any sides are reversible brah" shit. Took it at like 7pm, felt fine, went to bed around 12, woke up the next morning and went to scratch my balls and the morning wood which I'd usually feel was just gone. It's like my dick was no longer a physical part of me.
I regularly go months without masturbating and if I ever do cum it's literally no more pleasurable than taking a piss. I am a rare case admittedly but yeah, jfl at incel genetics. Reproducing while carrying the MPB gene is a crime worse than genocide.
