Medical Problems
First I would like to say, though I hope it goes without saying, that what I say here is my own opinion and not that of any medical professionals sanctioned by the Federal government.  I have read some interesting reports about the relationships between sexual abuse and health.  If I can find them I will add them later.  At this time though it is simply my opinions.

While there are obvious impacts on health due to childhood sexual assault, there are lesser obvious impacts as well.  I will address these separately.  If you have any comments or if anything here sparks anything with you, feel free to e-mail me.

First I would like to address the more obvious health impacts from childhood sexual and other sexual abuse.  I am going over these first to make myself realize how things impacted me not only mentally but physically, and so that people who see this can see these same things in themselves or others, perhaps as a warning for someone who sees these in a child.

     +   Due to vaginal penetration at an extremely young age, I suffered
          numerous vaginal infections such as yeast infections.  The contact
          alone, (not to mention the infections due to tearing, bruising and
          simple irritation due to contact and abuse) was enough to upset the
          balance or acidity and hormones.  This is in part why you see trouble
          with urination in children who are being abused.

     +  Urinary tract and bladder problems.  Including numerous and persistent
         infections.  Urinary tract problems persist for me to this day.

     +  A "trick" jaw.  Because of the size difference between a penis and a
         child's mouth, the pressure causes the jaw to be misplaced, especially
         with the force that was used in my case.  My jaw still clicks;  A constant
         reminder of the past .  When engaging in oral sex now willingly, I get
         sore easy, though I hear that is true for many women anyway and since I
         can't compare, I can only imagine if it is worse for me.  I would venture to
         say I notice it more.

     +  Vaginal and Anal bleeding.  These are fairly self-explanatory.  Whenever
         the delicate skin is abused in those two regions, there are problems.
         This leads to hemorrhoids very early in life and scaring of the vagina.

     +  Bladder and pelvic problems.  With the amount of force, the displacing
         of all the organs in the pelvic area happens.  Also, I had some very violent
         episodes (for example, one time my brother thought I was perhaps pregnant
         so he punched me in the stomach and put a great deal of violent internal force
         until I bled in an attempt to do a home abortion) that still give me pain and trouble
         today.  I think this relates directly to some internal problems I have with my
         Ovaries and Uterus.

Even if you can't find a direct link between some of the health problems I have and sexual abuse, the fact that my body was under constant physical and emotional stress and healing from multiple minor injuries my entire life weakened my immune system and exacerbated any pre-existing or unrelated health problems.  This along with the stress of keeping the silence and living with myself and my past ate me away mentally and physically causing me to come very close to death.  Below are some of the other and long-lasting health problems I have been facing and how I feel they relate to my sexual abuse.
