Can a large penis puncture the cervix?

No: However, if partners are incompatible there may be tearing and bruising, especially before they become accustomed to one another. This is something you could talk about as a couple with your physician.

No: No, that doesn't occur. However, if you are having vigorous intercourse in certain positions, the penis may bump the cervix, which can be painful for some women. Pay attention to your partner and make sure they let you know if a position is too uncomfortable- changing to a different position may be very helpful. Using lube to decrease irritation to the lining of the vagina is recommended also.
