How did they measure "penile circumference" over time? Is there a guy standing next to them with a tape measure?
really hot male lab assitant measures it closely
installing a glory hole in the lab for double-blind studies
Elastic ring that can measure how much it streched.
Makes sense. Albeit I find the idea of someone holding a tape measure more funny.
That's likely how it used to be done
It’s basically the same thing as a ring fit adventure, a strain gauge, though research ones are far more sensitive
These things are used in really sketchy therapy like conversion therapy. They were also used in pedophilia treatment in the 90s which was basically conversion therapy to track outcomes, basically exactly as what’s written here (though they wouldn’t present actual illegal material, just risqué material like pictures of kids at the beach or something). Penile plethysmography is the area and it’s still practiced in some places, though it’s pretty controversial because they’re evaluating sex offenders for risk of recidivism and viability of release which is always inherently controversial and other more obvious reasons
It is also controversial because sexual arousal is far from the only reason men have erections.
This study is an example, there's an alternate interpretation that affirms homophobia is actually the result of repressed sexuality, in general. Thus any sexual stimuli would be arousing. Thus causing an erection, regardless of the gender displayed, and irrespective of the person's sexual orientation.
This tracks with the fact that almost all homophobes are politically conservative, tend to be highly religious, or are very young and immature. They all coincide with environments prone to sexual repression.
The other variation is that anger also causes arousing.
This study was too small to control for those kind of factors.
Probably some sort of pressure cuff that they measured changes in air pressure, or something similar?
That's what I was wondering for quite some time for developing a recreationa..... aaaaah medical device using an esp32 that can control other hardware over Bluetooth. A sttetch sensor or pressure cuff might work, but it might be nicer not to have it work like a blood pressure measurement machine.
