What you have are called Genital Warts, those happen to men and women. It is within the STD spectrum, thus those "cauliflower" looking growths you mention are the warts. I suppose you had a pap smear by your doctor, this first link explains it very well and clearly.
Now this next link is not pretty to look at, these are pictures of how the warts look both in men and women.
Once you are in the page see the top and you will read Genital Warts, Anal Warts and Cervical Cancer, click on each and you will see the pictures.
You need to keep on checking yourself with Pap Smears just in case it becomes an HPV issue which if not attended to can become cervical cancer. I would be best if you had protected sex, you can avoid the dryness using a lubricant but protect yourself if it turns out to become a Cervical Cancer then you will know why you git it. Read the first link above and then if you are up to it look at the pictures. If you need further information check the following links:
I am sorry I have had to post the link to those graphic pictures but it is necessary for you to have first hand knowledge on the subject of your question.

From the symptoms they can be benign growths since the biopsy have come out clear. Skin tags can occur but it cannot be explained by growths inside the cervix. If you notice any more growths during the routine pap smear or pelvic examination then you should have a repeat biopsy done to rule out any genital warts. The virus causing genital warts may lie dormant inside the nerve cells unless reactivated.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
