I have had sex with a lot of women... Lost count. But believe me, I am not bragging as I will admit, the majority of these women either have low self-esteem, psychological issues (that I can handle), and are typically not the super hot 9/10. In fact I may not have even been with what most men would consider a 9 and certainly not a 10 my entire life (despite having such a large sample size)... But still, I am the definition of "quantity over quality".
And far as the notion that the chubbies give superb head. It is no myth. But it does not extend simply to chubbies, it is for any women who has low self esteem, you rarely meet super beautiful women who have low self esteem.
These women who have lower self esteem will love and swoon over any fragments of affection they can get. If an attractive, young, charming, stylish man is giving them affection, it really puts them on cloud 9. They often focus solely on pleasuring me as I have become their "prize"... You can convince these women to do ANYTHING and literally wrap them around your finger and all they do is praise you.
The last actual beautiful woman I had sex with (a couple months ago perhaps), literally did not give a $hit. Mind you I had to game the hell out of this one, I literally put in a ton of effort into raising her interest level to just have the opportunity. She just laid there, and when she gave head (which she was reluctant to do) she did not even put any effort into it. This is because she is use to getting it her way, does not feel as if she has to put in a lot of effort into a man. Certianly a beautiful woman may be different, certainly if you are a MASTER of game you can make them swoon over you and convince them that you are the prize. However, witih chubby women it is very easy to do.
