Now I don't actually have any real erectile difficulties.... but certain situations in the past have been challenging....
- condoms - I always struggled to stay really hard using them, especially with any pauses in 'action'
- prolonged lack of physical stimulation - like lying there giving a girl a good long DATY, I'd always be a bit soft after that....

But now - a dose of the good gear, and we're rock hard the whole time almost regardless.... and this is 20 years after the issues mentioned above....
