Why after intercourse does your cervix feels like it closes preventing penetration again?

Answer 1

During intercourse, unless you move oddly, the penis will not touch the cervix. The cervix is not at the absolute end of the vagina, there is another "pocket" behind it that accomodates "extra" penis. If you are lying on your back the semen will pool here and the cervix above it will dip down into the semen during vaginal contractions (during orgasm.) To attempt to draw a picture in your mind of where the cervix is imagine a sock. In a tube sock the seam is at the very end of the sock, but in a regular sock the seam sits above your toes. The cervis sits above the end of the vagina in the same way. The cervix never opens except when you are giving birth and certainly the penis will never enter it. That would be impossible without special drugs to relax the cervix, a truly long and flexible penis and significant pain. What you may be feeling is muscle contraction. There are several layers of muscle around the vagina and just like in men the tissues around your vulva and vagina become swollen with blood when you are aroused. There is even erectile tissue that forms your clitorus and is under the skin all around the clitorus. After intercourse that swelling does not always fade away as quickly as it does in men. In addition to the swelling often the muscles of the vaginia will contract after sex. In some women they may stay this way for quite a while. The best thing to do is relax and wait it out. You may find that walking or doing something while standing will help, or that thinking calm thoughts and relaxing works better. Possibly a warm bath, although you should be careful soaking in a tub after sex, you could get a UTI if you dont clean the area prior to soaking. Possibly you will just need some "loosing up" if you want to have intercourse again very soon. Try massaging the inside of your vagina with your fingers (use lubricant, maybe even warming lubricant.) If that is painful then wait. If it merely feels tighter than usually but not painful just try using more lube for the second round. :) If you feel this is a real problem that interferes with your sex life or is painful please tell your GYN. You should be seeing him once a year for a PAP smear, but he will probably field phone calls during the rest of the year and may even ask you to come in to see him.

The cervix undergoes changes during sexual arousal and intercourse, including softening and moving to allow for penetration. After orgasm, the cervix may contract and firm up again, making penetration difficult or uncomfortable. It's a natural response and varies from person to person.
