yes 3 inches is enough to pleasure any virgin
I think your asking if you can get a woman pregnant with a 3 inch penis. If you produce sperm you can usually have a baby.
3/4ths of an inch
It depends if your penis is erect of flaccid. A 3 inch flaccid penis is average, however a 3 inch erect penis is slightly below average for a 14 year old. We cannot say what size it will be when you're 21, as penis' develop at different rates.
It depends on how you use it.
Penis size can vary widely and what is considered "big" is subjective. A soft penis size of 6 inches is above average, but ultimately it's about how you and your partner feel about it, not just the measurement. Communication and mutual pleasure are key in sexual satisfaction.
yes if its before puberty then yes
some can be, but it will be very difficult to find one
If it is large enough to successfully urinate, stop worrying about. It's fine.
the average size of a mans penis is around 6 inches, the vagina only has sensitive nerves for pleasure in the first 3 inches of her vaginal opening. This means even if your penis is only 3 inches then you can still pleasure her satisfactary but there is toher ways of pleasure without penitration, you could use toys, give her oral sex etcetera... i have quite a large penis myself, with good girth, and in my experience a woman always prefers the girth, not the lenght, as this can be uncomfrtable for them if it is too long!!
do it and find out then let us know
Unfortunately you will not be able to satisfy your wife, or any woman, sexually with a 3" penis. You will have to work on your other skills such as touch, caressing, oral, etc. Even 2 inch penis is long enough to reach the G Spot, so work at it - you will be able to satisfy her. Good luck!
Any size can get a woman pregnant.
