I am a big guy ( about 6'8" ) and am almost 20 yet I have a small penis for my size ( 5 inch ) how come and is there any hope it will grow more ?
Overall, body size doesn't influence penis size.
In other words, plenty of tall men have average-sized penises, like you, and plenty of short men have larger-than-average sized penises. Same goes for weight: penis size isn't influenced by body mass, either.
At the age of 20, it's pretty likely that the size penis you have right now is the size you're going to have. Given it's a perfectly average-sized, and presumably functional, penis, that's nothing to worry about. In other words, you're perfectly normal. I don't know what your orientation is, but study after study makes it pretty clear that the only group who are invested in big penises -- or penis length, period -- are men. Ruling out women who aren't interested in sex with men or sex with penises, period, given that the vagina doesn't really have nerve endings past the first few inches of the opening, that isn't very surprising. So, if your concern per your penis size is about sexual partners, it's a misplaced concern -- in other words, these worries are more in your head than in anyone else's.
Take a look at some of the findings of that 60-years-long review I linked above:
• A survey of over 50,000 heterosexual men and women found that 66 per cent of men said their penis was average sized, 22 per cent said large and 12 per cent said small. 85 per cent of women were satisfied with their partner’s penile size, but only 55 per cent of men were satisfied.
• Two studies reported that 90 per cent of women prefer a wide penis to a long one. Other studies pointed out that the issue of male attractiveness was complex, but that penile size was not the most important factor for women.
• Small penis syndrome (the feeling that a penis is just too small) is much more common in men with normal sized penises than those with a small micropenis with a flaccid length of less than 7cm (2.7 inches).
• One study found that 63 per cent of men complaining of small penises said their anxieties started with childhood comparisons and 37 per cent blamed erotic images viewed in their teenage years. None of the men studied actually had a micropenis.
In other words, this is a body image issue, not an issue of how big or small a penis actually is, so if you're feeling unhappy or funny about the size of your penis, the answer is to work on your body image, and really examine that, rather than looking to your penis to grow.
