Penis etiquette    

As long as it's clean, not full of hair seriously even if you are clean I don't need a bunch of hair tickling my nose or worse in my mouth so hear this guys if the hair grows up the shaft tend to that garden!  
                 If you are very shaved but have horrible razor bumps expect us to take a good long look before partaking in BBJ if offered,  
                     if you are unusually big or have been told you are believe it and it's good to have a few of your own magnums just in case.  
                                            Do not accidentally try to slip Not cool guys, and we get that game.
If you are uncircumcised visit the restroom pull it back and clean it up, if you want good BBJ  
if you have a history of only one pop tell a girl so she can have good timing. Likewise if you have problems finishing let us know.
Don't play the oops I forgot to say I was close game when receiving BBJ also not cool.  
                         There is the saying 'it's not how big the boat is it's the motion u put in the ocean' or something like that, guys that doesn't mean you should try and stir the vagina  especially when you are big, if you are big and she is tight don't try to stir anything also not cool. I think too many guys mostly younger ones get stuck on their size issues.
Hear this gents your big dick doesn't make you and your small dick shouldn't hold you back personality,how you treat us matters so much more.  

There is so much fun to be had with sex and sex play, don't be afraid of toys or learn how to eat the pussy even if you don't know how,  
practice makes perfect.

To backup what Mzchievous says.  This whole big penis thing is so overrated.  You guys watch too much porn and falsely believe big dicks are better and make you more of a man.  Big dicks hurt and make us sore.  You're not the only dick I'm seeing that day so a little smaller and less pounding my vagina for 30 minutes straight would be appreciated.  Feel free to offer some oral, love that.  And a double thank you for bringing up the uncircumcised thing.  You guys REALLY need to clean that thing well and often, cheese dicks are disgusting.  Clean it and I'll do almost anything you want with it and to it but if not you're going covered BJ or next time you contact me I'll be "too busy to schedule with you".

As far as penis size is concerned, someone once told me they'd rather be tickled than stabbed.
