Maybe if you have sex more then twice a day
The penis has a rod like shape so as to match the internal shape of the vagina. This helps in the effective delivery of sperm to the egg, which is located inside the uterus or fallopian tubes.
Aside from surgery there is nothing you can do to change the shape of the penis.
A cow's uterus is an irregular shape, but it certainly does not look like a woman's uterus, which is triangle-shaped. A cow's uterus is divided into two "horns" which divide out in a V-shape if looking at the uterus from above.
Typically no, the uterus is removed, this is not factored into sex, unless the penis is very, very huge!
The Size of your penis or smaler
The uterus is the organ behind the cervix in a female. It has nothing to do with penis size, as the penis never enters the uterus. The penis enters the vaginal canal, which is very elastic. The cervix is at the end of the vaginal canal. The only time the cervix opens enough to allow entry, is when a woman is birthing a child.
No - if a girl has a penis then she is physically male and thus doesn't have a uterus, as such she does not menstruate.
penis, vagina, testes, ovaries, uterus
Yes, it is dangerous
No. The vagina can stretch to accomodate the biggest penis and it is closed at the top by the cervix through which nothing larger than a skewer can pass. It's possible, but probably the unlikeliest thing to happen during sex.
No.
no. the penis will probably never touch the uterus as the cervix is blocking the only route. all that needs to happen is to ejaculate inside the vagina or even on the outside and it drips in might get a girl pregnant
