Why isn't PE mainstream?
If this stuff works why don’t we have gyms dedicated to PE? Or at least physical education course for it. There could be an instructor to teache people how to work out the penis. It could basically be like taking a yoga or pilates class at Bally’s. Granted it would be awkward having a bunch of guys meet up to work out their cocks, but people who are open minded and mature wouldn’t care. Or maybe have personal trainers, who do private sessions. It could lead to the creation of new jobs.
