Natural Function

[Smetro]

After more than 7 months, regular sex and twice daily cycling:

As time has passed I have found that depending on the sexual situation, both 'feeling' and blood into my penis have returned to some degree.

If I am 1/3 inflated and my GF 'interacts' with me sexually (physically or merely suggestively) the old 'twinge' and blood flow happens.
Enough for vigorous sex?...no not really. But reminiscent of days gone by? Yes.
All part of the adaptive process of having this amazing piece of technology inside me

It said, in part:

"Conserving cavernous tissue during PPI surgery can help to preserve residual sexual function and penile length. And this can be achieved by withholding unnecessary corporeal dilation in primary implants, where corporal fibrosis is minimal. In a randomized study of 100 patients with PPI, half had corporeal dilation while the other half did not. Average postoperative penile length improved by 1.1 cm in the group without corporeal dilation and decreased by 1.2 cm in the group with corporeal dilation at 6 months (P<0.05) (13). A more intact spongy cavernosal tissue can become engorged and contribute to a more natural response during sexual stimulation."

In talking to Kramer, he no longer dilates as a matter of course. So indeed, the tissue is compressed, but can retain function.
