Is penis size hereditary?

[frenchteacher]

This might be a silly question, and ultimately I'm sure it's right that 'size doesn't matter, it's what you do with it that counts' or 'every penis can give a partner sexual pleasure', but to what extent is penis size hereditary? My DH is a little over 6 foot tall (188cm), but rather modestly endowed for his height and terribly anxious about the size of his penis. So much so that he refuses to stand at a urinal or change in communal areas at the gym or swimming pool in case anyone should notice (as if anyone else would be interested!). I don't wish to belittle (no pun intended!) what, for him, is obviously a very real anxiety, but his obsession (not any inadequacy of penis size!) can sometimes have an affect on our sexual relationship. He is always asking me if I'm happy with his size, how he compares to previous partners etc., which, frankly, can be a bit a mood-killer. DS is only just 4, has a lot of developing to do and is obviously untroubled by any such issues at the moment. My concern, though, is that if penis size is hereditary, that he might inherit his father's neurosis, and I would HATE for that to happen.

The size of the flaccid penis is immensely variable (how cold it is etc) and unrelated to size when erect. Unless your DH is in the habit of frequenting urinals and changing rooms where the display of erections is the norm, then this is a question about anxiety not anatomy.

@EdithWeston Absolutely! And in my fairly limited experience, I would say there is nothing at all unusual about the size of his flaccid penis. His erection - again in my limited experience, but also having been party to a little of my DH's research on the internet (gospel truth at all times, of course!) - I would say might be a bit smaller than average, but functions perfectly well and is the cause of no complaints from me.
