So, i want to preface this by saying: I'm not gay.  But I want to know if penis size and the genetics of testosterone/musculature are related.  In other words, are people who are naturally inclined toward building muscle likely to have larger genitals?   But I can't find any pubmed articles on this or any physical journals that broach the topic.  So what's the next option?  Google Image Search naked bodybuilders - a person making a living as a bodybuilder, even at the amateur level would most assuredly be naturally inclined toward musculature.  But I don't want to do that because I'm not a gay.  I swear to god.   What do I do?  
Sincerely, not a queer I promise.
