Penis head types

The three shapes are:

Bottle - A penis where the head is slightly smaller than the shaft

Prow - A penis where the glans is heavily indented on the ventral side causing the glans to appear to swoop upward a bit.

Blunt - Your classic mushroom where the glans is larger than the shaft.

These were compiled by Gordon Schindler and published in the 1950s in a book for adolescent males. It's a surprisingly good book, very frank and illustrative for its time, and (somewhere) I have a copy of it.
I still fail to see this whole "prow" thing.

A "prow" is the front part of a ship that curves up (the part that breaks water). How does this describe the overall shape of the penis or the shape of the penis head I still fail to see.
 
I remember that too. I recall one head was smaller than the shaft.



Sometime back in the 80's I read a book that claimed there were three different types of penis heads(glans). I have forgot the book and forgot the types of glans they describe. Does anyone have any information on this? What type of penis head do you have? I've seen enough mushroom heads and think they were described by another word. I do think one of the types was "bottle", whatever the heck that means. Thanks.
 
Reading this I tend to think that I have a helmet head, How would you describe your's Plug it in?
I would say prow from the one pic you posted
No, I'd say you have a mushroom. The head is bigger than the shaft.

Mine is a helmet... because it tapers down then the head blooms out.

Prow is not a penis head type, it is is a penis shape...
 
I agree with all your assessments Plug it in! as always you are right on! maybe you should oat here again the guide we use and clear up the prow thing.
