It is fun how easy you guys are to shock with that. You keep saying it is stupid, but you all talk about it, hahahahahaha.
Bigger penis might lead to be more self-confident.
It also depend of the penis, some are small and get way bigger with a boner, some are big and get less bigger with a boner.
Some get hard boner, some not hard.
Some can *** multiple time in a row, some cannot.
Some have big girth (and yes it seems to make a difference, I had good comment about this, while my length is not monstruous, I would say above average but if everyone say that, maybe we are the average? or the other just stfu)
etc.
And it could make a difference to keep your women I guess, especially in LTR.
I believe some girl will stick with a men solely because of good sex, maybe not forever, but that will extend his time ;-) [same go torward girl that are horny beyotch]
