Does anyone have experience with tracking nocturnal penile tumescence?

I came across this consumer device. Not sure if anyone has experience with this or anything else?

“underwearables” :rofl:

Could be useful if you’re undergoing treatment for erectile disfunction, or for “research”?

I’d also be very amused if they were able to estimate sleep phases more accurately than Oura…

I think this device is used for maintaining an erection, not detecting an erection. You might want to consult with a urologist before strapping this on at night because one of the common warnings with these types of products is nerve damage and an associated loss of sensation from excessive use.
