Sorry, I accept the opinion of every user here, but as a bull, I have to say that ALL THE WOMEN I met during my life told me that sex with me was completely a huge difference compared to their previous lovers, or in the case of a married woman, to her husband.
But as I already wrote in different posts before, when you are above average, you need to be very careful. I don't know how other guys do it, but in my case, I can say that IT TAKES A WHILE until I can start having normal sex with a woman. Not all the women are the same, not all teh vaginas are the same. But IN GENERAL, a thicker penis is more pleasant than a thin one. Longer doesn't mean better if they don't enjoy cervix stimulation.
