If you are referring to physical pleasure a bigger penis size will provide while having sex, than there is a very definitive answer to this question. YES.
It is specifically better to have more girth so that it better stretches the walls of the vagina.
Now it’s not saying that lack of penis size will cause you to suck in bed. No, it might even make you better because you will have to spend time learning how to actually get a woman off. You might be a more attentive lover and a better mate since you will not want to have to go out and find another woman to get to accept your tiny penis.
