Men with average to large sized penis' often do reach the end of the vagina in certain penetrative positions. The mans penis hits into the womens cervix which is the opening to the womb, where babies are grown. This can be very painful for most women, so if you find you are hitting your girlfriends cervix, you should probably try not penetrating so far into her.
The usual method is through sexual intercourse. This is when a male puts his erect penis in the female's vagina. And then after moving it in and out for a while, he ejaculates and releases his sperm inside her body.
That is usually refered to as the Missionary Position. It involves the woman laying on her back with her legs open, and the man on top and between her legs. The insertion of the penis into the vagina then takes place, and the man will move in and partially out repeatedly until he (and hopefully she) reaches orgasm.
Women don't really ejaculate the same way a man does. However, when a women reaches climax fluids can get released that serve to both lubricate and change the Ph of the vagina to make it more "hospitable" for semen.
The woman's private area is collectively called the vulva. The part at the lower end of the vulva where a man inserts his penis is called the vagina. The vagina is also what is commonly called the birth canal.
The only way for a woman to get pregnant with a man is if his sperm end up inside her vagina. So no.
to put it bluntly, it means he thinks your vagina is 'good'
A man has a penis.
a *mangina, is when a man has vagina. Simple.
Hermaphrodite.
It depends on the position. In positions where maximum penetration can occur, such as doggy style or missionary, the end of a normal sized penis (5.5 to 6.5 inches) will reach the end of the vagina (the cervical fornix) when the penis is all the way in. This has been confirmed by using CT scans and MRIs.
Due to my past experience with such matters, I can tell you that the man will end up with very red and sticky fingers.
Meaning sexual intercourse. The man puts his penis up the womans vagina firmly. This is also known as "making love". You could have a baby but if you use a condom you are more safe.
