For most porn stars Viagra et al is useless, because you still need to be "in the mood" for it to work. Most male talent are so desensitized to sex, that they must resort to other substances that they inject directly into the penis, like Papaverine [0]. Of course that comes with its own set of challenges, like the risk of prolonged erections, called priapism [1], which sometimes can only be stopped by surgically draining the stale blood from the penis.
I'm looking for research into the neurological basis of arousal (not necessarily erection, which is only a small part of it). If anybody knows, spam me.
