I aslo think that visible penis lines are not appropriate. Everyone thinks that breasts and vpls can be associated but thats not the same. Breast are one thing but most people would consider it inappropriate for a woman's nipples to be visible through her clothes. Same thing can be said if you can see a man's dick head or the complete outline of his penis showing through his pants. If a man's clothes fit correctly and he is wearing underwear you should not see the outline of his penis unless he is erect no matter how big it is soft.
Interesting theory, but surely somebody can offer some explanation as to how it may not always hold? Why exactly must a woman's nipples never show through clothes? Can you define "show?" Is "showing" a quarter inch deflection from the normal breast curvature, or a half inch? What about women who have bigger nipples than others?
If a man's clothes fit correctly? What? Loose and baggy for the big-dicked guys? What of growing lads who's pants used to fit better, but now they almost need some new bigger pants? Would you care to buy some for them?
If some school has a dress code, and they decide that wearing shorts is okay, just so long as they aren't short shorts that aren't modest enough, a ruler might be a useful tool for evaluation/enforcement. But what in the world would you do with a ruler for regulating VPLs? Make everybody have the same sized penis? Smack people over the hand with it, until they reposition to a more "modest" sitting position, when they didn't even notice a bit too big of a bulge pucker?
And what would you do with a woman's nipples showing, when she breastfeeds? I hear it's common for women to breastfeed in public in developing countries that still happen to be more pronatalist that we are these days. People eat in public, and we say that more women should breastfeed. Oh, but they should cover up, some prudes may claim. Perhaps so, but how many excuses could I did up, why that may not always work? Forgot the baby blanket. Baby tosses it off. Too hot outside. Didn't plan to have to wait so long. What baby blanket? Was only positioning allowing a glimpse. Well at least nursing mothers have an excuse.
And have you ever heard the whole growers versus showers thing? Some guys are almost as large soft, as hard. The bulge may be nearly the same, other than lacking apparent stiffness or "tentability?"
Now I don't usually show all that much bulge, as I am a grower, not a shower. But even my Dad has said something about positioning it right I think, because I tend to have a bit of a big dick myself, that can easily enough show a bit of a bulge. And I have to shake it good at the urnal, to get out all the urine dribbles, one reason I like better to visit the restroom at home than in public places. Seems like there is a bit too much penis shaft for urine to linger and dribble out of after putting it away.
But I am not that quick to judge, and have no objection to a woman's nipples being so big as to "show" a bit, nor to mothers breastfeeding in public. And some guys have longer penises than mine, so of course they may show some. Look at all the photos floating around of celebrities sporting bulges. What's the big deal? You have to stare rather close to see those little minor bulges. The world now has over 3 billion human penises in it. What's wrong with a few minor bulges, that would seem to be rather inevitable?
Pregnancies really bulge conspicuously, and we all know what makes babies, right? But it should be acceptable and fashionable to bulge conspicuously "great with child," because it's a very "good" thing to bring ever more precious human beings to life.
Like I said, bulges, even reproductive-related bulges, are a fact of life. Humans are sexual creatures, and often said to be among the horniest of God's creatures, curiously enjoying being constantly "in heat," able to breed year-round. And humans would seem to be among the most populous of large mammals as well. So there will be bulges, and they will be noticed, even if politely overlooked by most.
Even the name of the discussion thread, suggests that natural penis bulges are sometimes impossible to completely hide. It has to go somewhere, and some people are obviously well-hung or well-endowed.
