What would cause bleeding during sex?

Thanks for your question. I'm glad that you got checked out and that your tests were normal. Bleeding during or after sex is a relatively common occurrence that can have many causes, most of which are not serious or dangerous. There are some instances when medical treatment is necessary, however, so further evaluation would be helpful if this bleeding continues. To better help you, I consulted Dr. Gary Glasser of Atlanta Gynecology and Obstetrics in Decatur, Georgia. Dr Glasser shares the following information:

Bleeding after sexual intercourse (also called "post-coital bleeding") is not rare; up to 10% of women have had this at some point in their lives. Abnormal bleeding can bring up the thought, "Is this cancer?" Fortunately, the risk of cancer with post-coital bleeding is not common (thousands of women will have this type of bleeding for every one cancer found).

Should a woman have an episode of post-coital bleeding, she should see her health care professional. The vagina may be the source of the blood, as small tears from intercourse may occur at any age (but more commonly after menopause due to the loss of elasticity or "vaginal dryness" as it is commonly known). The cervix may have a benign (not life-threatening) condition where the cells usually found on the inside the cervical canal are on the outside of the cervix. These cells are sensitive to touch (such as during a Pap smear or intercourse) and may bleed. Any vaginal discharge should be cultured and looked at under a microscope, since infections such as chlamydia can cause bleeding if they affecting the cervix. Also, benign cervical polyps (they look like little skin tags on the cervix) can easily and painlessly be removed in an office setting.

A Pap smear should be done if the woman is due for one (depending on her age and previous Pap smear history) and any lesions on the cervix (or the vagina) should be biopsied to evaluate for pre-cancer or cancer of the cervix.

In the majority of cases, however, no cause is found for the post-coital bleeding. If the bleeding persists or there is bleeding other than post-coital, a further evaluation of the cervical canal and/or uterus should be done by a gynecologist.

    Nice comments very grown up and caring. I had a polyp. It bled. I was scared for days it was cancer. Thankful it wasn't.

    Yeah bleeding may not be a major problem but it could be. For example, I was only 23 at the time but this happened to me and I ended up being diagnosed with a serious issue that could have lead to uterine cancer. It is fairly rare in females my age (more likely to happen to women in during their menopausal years) but it did happen to me. Now I have biopsies once a year. I had surgery and I have been on medication ever since. Any time you are bleeding for "no reason" it isn't a joke.

      I too had this. Had to have the cervix "de-nuded" of the surface layer. Burned inside and out. It was uncomfortable but it remedied the problem for a few years anyway... Until the pap smears started coming back funky. Then I had to have a hysterechtomy. Cervix removed as well. It was the start of cancer. Nothing to fool around with.

      I had it too, and no cause was ever found. Twenty years afterward I am still just fine. So, definitely see your doctor, but the odds are great that nothing serious is wrong.

      Hi Kate, I really dont understand why you would put such a comment like that when people are trying to get helpful information to find out what could possibly be wrong with them. I guess you are the person who has not had a medical problem to deal with in your life and I guess you look at yourself as BLESSED yet you will put something like you did on a website when people are just trying to get help. We are not the idiots yet look in the mirror and you will certainly be looking at the BIGGEST IDIOT of all time.

    I have this problem, especially during intercourse. I have been to 2 doctors, however, I have Blue Shield of California. My last doctor sent me to get xrays, blood tests, and so on. After about 1000, out of my pocket because Blue Shield of California would not pay for the unecessary xrays, and my return visit, I still have the problem, first doctor told me I need to lose wieght and the second one said its normal. Talk about pathetic!

    Why wasn't endometriosis mentioned? That's the most common reason for pain and bleeding with intercourse. One in 10 women has it, yet it's hardly discussed.

    It is happening more and more during sex. It is when my boyfriend doesn't take time to "warm my oven" that it is apparent. When I'm aroused it is not a problem. Why?

    I was having a lot of cramping with orgasms or sometimes even just from getting worked up. I went to two different doctors and they both said that if it wasn't bothering me all the time, I shouldn't worry about it. They told me just to take tylenol before sex. I assumed it was my IUD and had it removed. Now, I'm still on a progesterone-only birth control and the last two times I've had sex, I have bleed during sex. It wasn't rough or anything, and I am not on my period. I'm wondering if these could be related or if something serious is going on.

    Please email me if you have any information. I'm 18 years old and have had a regular periods, or what would be regular to me because I know when to expect my period for the past year and a half. Me and my boyfriend had actually had intercourse in between my ovulation and most fertile days. July came and in the beginning of the first few weeks I was waiting for my period. We ended up deciding well we will have some intercourse on the 16th of july. He immediately pulled out within a few minutes, if that. I asked him what was wrong and he said it feels different. & that's when I noticed the blood. and for the next 2 days I had cramps that we're just about equal in pain to my menstral cramps. Then they stopped and I continued to bleed with no pain.(mind you during my menstral time I do bleed heavy and I cramp badly.) leading up to Yesterday, the bleeding got lighter and finally stopped and then I would only bleed when I went to the bathroom to pee. by 1 o'clock yesterday I had passed a semi large gray clump. I couldn't exactly describe it. After that there was really no more bleeding. About an hour ago me and my boyfriend stupidly decided to have intercourse. He said it didn't feel different but when I checked I was bleeding again accompanied by plenty of clear mucus. it wasn't much blood and this whole time of bleeding found July 16th til today I can say it was nothing like a normal period. today would make my last day of my so called period.. If that's what this is. if it's a late period I'm curious as to why because normally I expect my period Within the first 2 weeks of the month. never later than that. now I frequently feel like I have to pee. I have no idea what to do it stressful it's confusing I just wanna know what's going on with my body. please email me back if you have any ideas or questions that could lead up to any kind of answers I would appreciate anything. tparenteau08@gmail.com

    Well. I had this problem for a year and a half. Dont anymore though. Went to several doctors who all gave me yeast infection meds. Was wondering why they never worked. Was worried. One day told my girl about it. She told me to try take folic acid tablets. Believe it or not. it worked. I guess i had some folic acid deficiency. but i thank God (and my girlfriend) that the problem is solved.
