The cervix is a few inches in, past the vaginal opening. It it attached at the end of the vagina and to the uterus. It is actually the opening of the uterus. It holds closed to keep a baby in the uterus, it also opens to allow the baby to pass through when it is born.
The Uterus/Cervix "move" (sort of) throughout a woman's menstrual cycle. At some times it is closer to the vaginal opening, other times it is further in the vaginal canal. During sexual arousal, the cervix/uterus lift higher to allow room for the penis. Sometimes the penis can hit the cervix, which can be painful for the woman.
You can think of the arrangement of the vagina, cervix, and uterus this way. Imagine a pear, and a tall glass. Put the pear in the glass, upside-down so that only the thinnest part of the pear is actually in the glass, and most of the pear is outside and ontop of the glass. The glass is the vagina. The part of the pear that is in the glass is the cervix. The part of the pear that is outside/above the glass is the uterus. The vaginal opening is the bottom of the glass (you have to imagine it being opened at the bottom of the glass).
Does that help?

Reason: 1 more sentence for clarification
Yes, it is possible for it to be painful for a woman to have intercourse after having had surgery on her sex organs, especially if the doctor hasn't released her for such activities.
After a doctor performs laser surgery (or other surgeries on the vulva, vagina, cervix, uterus, etc) the doctor gives restrictions on anything entering the vagina for several weeks. Depending on the extent of the surgery, the restriction can last 6-8 weeks (like after a hysterectomy). Generally, there is a 2-4 week restriction after laser surgery.
In addition to the pain, having intercourse too early after surgery can cause complications later on because the tissue hasn't healed properly. Even if the doctor has given the OK for sexual activities, it is up to the woman to know when she feels ready to resume intercourse. The doctor may say everything has healed well, but she may still have pain or discomfort.
If your girlfriend says she is in pain or discomfort, trust her.
