Exactly and most talk bullshit anyway, plus most men incl me at one time have been insecure about the whole penis issue, so it doesn't go hand in hand at helping each other.
Whats to big is when it gets to a stage that the male cant use his size satisfactory any more, it becomes too difficult to get engorged and erect, and it starts to loose its erection quicker. The penis may be hard to penetrate inside the women because its so large and more foreplay is needed or a looser women etc. The women may not like it, many variables play a role in answering this question 'What is to big' and I don't think any more that a measurement can be placed on it, as eveyones different ... every guy uses his dick differently and can or would use his larger unit better, worse or whatever than the next guy ... same true with the women or indeed the man being penetrated, as they may or may not be able to handle a certain size, be experienced enough or turned on enough etc.
I think that many are wrapped up far too much in the black myth and I see it all over facebook, the groups that say black men are better lovers, better at lasting, better at kissing, bigger dicks, cook better burgers and iron the clothes better .. you get my drift .. its BS and the inexperienced or just pathetic jump on the band wagon, that incl many young easy led girls these days that don't know their head from there arsehole!
One guy I heard in the canteen at college the other day said his cock is 11 inches long and I laughed in his face and said 'yeah that's from your arsehole to the tip of your dick chump' and he went bright red.
Whats to big? hey for some its never to fucking big lol they are so insecure that 15 inches length would not be enough or 8 inches girth. I often see comparisons made to child birth and vagina size and again what BS because its hardly pleasurable giving birth from what I'm told, so a cock that size isn't going to be ''rocking her world'' so lets get real guys and think REAL ... what can you handle? what can your body handle? what can the women handle? what indeed do you actually need? plucking a figure from thin air with all my wisdom and years of experience in the field I would confidently say that 7 1/2 inches length with 6.2 inches girth will satisfy virtually anyone ... male and female, the user and the one being fucked.
