For some years, Ive participated in a discussion forum at www.ihiqs.org, an online high IQ society that requires passing a test for membership.
Unfortunately, I can not vouch for the size of any dicks over there. Id do my part for science, if called to duty, although Im not real smart and may have to measure again and again to be sure I get it right especially the big ones.
Bet Id find IHIQS members members reflect the full range.
I can say Ive seen convincing evidence of hung guys around here pictures only unfortunately, Id be happy to perform some cross forum research - and have read LPSG members posts. Although discussion topics differ, theres plenty evidence of men here who are both hung and smart. A more narrow subject range here, notwithstanding, many posts could be interchanged and no one would ever give it a thought.
Oftentimes, I find that having a huge dick equates to needing glasses.
