Vanity. The same reason women get fake boobs.
I have heard of a study in which researchers did the measuring. Took the inflation out of self reporting. In the study the average was under 5 ". Only 10 % were greater than 6 in. It doesn't leave that many with 7 in or more. On 1 website the women started a top 10%club. To get in guys had to submit a picture with a ruler. Most of them that made it were less than 7 in. Hardly any over. Overall not as many given the claims by guys of how big they are. Most self reporting studies have come up with an average of 5.5 in or less.
For me I am a little over 5 in and decently thick.
I think it depends on the woman little women little tits. Bigger women bigger tits.
Why do women try to get to a size 0 and the go get fake tits thinking Ds with look right. It's like a frankenstien movie.
When a woman is naked her tits should look natural( perky a little sag) and not like helium balloons defying gravity.
Natural tits can be to big. Anything over dd is not good
I know this is an old thread but I would guess there are other problems in the relationship. I would say there is a divide between you too outside of the bedroom. It can be hard to be sexual with your wife when you are harboring ill feelings.
There is a second idea. He who has the gold rules. In the case of sex women control it for the most part. You want sex how you feel it should be. In many cases the woman doesnt take the time to understand mens desires and actually crush his ability to openly express his desires.
As an example. Men are very visual, it is how we are created and there is nothing we can do about it. But many women are very self conscious about men looking at them naked. I was told by more than 1 woman that they were uncomfortable to totally open up for a man. We want to see all of you. We buy lingerie and she wont wear it or if she does she jumps under the covers. So your wife wont be open with her body so you look at porn.
Also when our sexual desires or curiosities dont align with yours you call us perverts. Much in the same way the pc crowd uses words like racist to make people out to be something they are not. Pretty soon you feel alienated. You take some sex but you also find your outlets.
I think you need to find out why he is no longer interested in sex with you. I think you should make a deal that he stops looking at porn in return you find out what it takes to get him back in bed.
I think the breast size should fit the woman. A small woman should have small breast. A cups are fine on a very skinny woman. A bigger woman should have larger breast. Fake breasts generally look bad. Breast are to big when they start getting above dd.
