Sex should never be forced. However, if it is consensual (a.k.a rape fantasy or rough sex) the vagina will tighten and try to push the penis out. This is why rapes are so painful, physically, it can tear the inside of the vagina and sometimes the clitoris. If the hymen is still intact during the act it makes it even more damaging.
its possible you can get pregnant and if the penis was forced in the vagina it would be consider rape.
The vagina is made to fit many differant sizes of penis. If one too big for the vagina is forced in it can be very painful and can even tear the opening. If your penis is too big for your girlfriend than I recommend easing it in or using "tools,toys" to increase the size of the opening to support your size. Think of this that vagina that your having sex with is made to have a human being come out of it and even out of the cervix which is much much smaller. As long as you are gentle with your girl and take care of her emotionally and having foreplay with her before actual penitration it will be all good. As far as length goes depending on the woman vaginas can support penis's as long as 10-14 inches, no lie. you wouldn't think that it would but it goes off to the side don't worry about causing internal damage because its very very unlikely unless you ram it in there as hard as you can, and your penis is humungous. Take it easy and good luck.
It works just fine. The vagina can fit a baby so a penis is no problem.
Penis --> Vagina = Baby
From my experiences, no it doesn't. The only thing that happens when a girl "squirts"is the vagina gets wetter. Don't worry, you'll be okay. Be careful though, don't be stupid.

each man is different and no one can feel the same way you do
