Are we for real? There has been separations attributed to the penis size? A part of me wants to believe that is just the internet making stuff up or taking things out of context but is so ludicrous that is probably true
The average penis size should be good enough to physically satisfy an average woman, how bad you may use it is up to you. In mainstream porn, we see a bunch of actors with humongous penises as it is all fetished and catered to a primary male audience, because as someone already said: it is the male fantasy. So, unless you plan to become a porn actor it is a desired trait alas not mandatory. Also, mostly of what we see in porn is a performance, actors need to take some of the more uncomfortable positions to have sex only to accomodate to the camera man to capture the penetration, for which it is a plus if you have few extra inches of dong because it will make it less likely to break the inmersion by accidentally slipping out of the vagina
