"hardline"

Just a quick question guys...

I get what flatline is, is hardline just the opposite where you have like a super libido?

and as far as the shrinkage goes in the flatline, is it the opposite effect with hardline like stronger erections and I don't wanna say bigger but at its max potential? or does it just kinda go back to how it was?

not sure if it matters but I don't have any issues with ED, I'm doing this to see how it will effect my anxiety, confidence, and energy levels.
