Society dictates that these days a man needs some gargantuan sized weapon if mass destruction to have a woman appreciate his penis and the truth is. Not even a fraction of the women who want that monster can actually handle that monster. Again be comfortable with what you have if your partner is judging based on your size then maybe she or he is not for you.
There is this ridiculous thing these days where people are not being comfortable with their own bodies. Frankly I find this to be flatly ridiculous and a insecurity people need to get over.
