I know what you mean. :eek: But it might be relatively painless and safe. It would not be the most extreme thing I have done.

Searches with ones drug of interest and Pharmacokinetics will often turn up what one is looking for and this:
MedlinePlus - Health Information from the National Library of Medicine
is also a good general source of info because it is compiled by the US Government. Okay, that sounds bad but in this case it is good. :)

I am mostly just thinking out loud here. I am wondering if erection would be spontaneous with a high local concentration. I really don’t know. As a related side note, a very well respected and knowledgeable member here sent me a link to this:
Levitra induced hard on Bigger then F.S.B.P.L.
and told me that he and a physician friend of his have found that they get extra girth and a particularly taunt glans. In part, that is why I have the PDEIs and Levitra in particular on my mind.
"Vardenafil (Levitra) has a similar duration of action to sildenafil, but is more potent and selective biochemically."

T supplementation completely restored PDE5 expression, erectile response to ES and responsiveness to PDE5 inhibitor."
penismith - The Penis (smooth) Muscle Theory
You should read that thread, it contains a lot of great information. I also realize that I already know the answer to the electronic stimulation question.
"Erectile function was evaluated by monitoring intracavernous pressure (ICP) following electro-stimulation (ES) of the cavernous nerve and intracavernous injection of NO donor, sodium nitroprusside (SNP)."
And what is this sodium nitroprusside? Hmm. Both quotes are from that same link.

Damn good question. These night time erections are somewhat different biochemically from horny boners though so I don’t know if stimulating them would have the same effect.
