So what does that accomplish?
People like the feeling. Also theoretically can be good to increase blood flow to deliver more nutrients to the muscles. Then there
is the possible performance increasing aspect. I remember reading that WADA was testing athletes for dick-drugs despite them not
being on the banned list, to discover new doping trends, and a huge percentage had erection drugs in their system. They were not taking them for sex.
For enhanced athletes they lower blood pressure which is good if you have mildly elevated BP. Plus they can alleviate pissing problems from swollen prostates due to steroids.
