Shhhhhh ...he may hear you.
The experience of any trauma can leave subtle (and not so subtle) issues of post traumatic stress in which any thing that represents or symbolizes the trauma and actual trigger a re-experiencing of the original trauma (almost like a complete age regression).
Touch becomes a powerful associated learned trigger coded deep due to the body chemical during an intense one-time learning experience.
IMHO, if you have not already discuss that traumatic experience with a profession with an expertise in rape, please contact the local rape hotline and they can often direct/refer you. We we don't think we need to talk about it is when we often do.
You are right that training is not therapy, but it is an opportunity to disconnect the associative learning of touch/contact/intent from past experiences and re-wire them with how you would like to think, feel, and behave.
Like any other demon, we must have the courage and compassion to stare it in the eyes until it blinks first. What ever you have to face, you have already survived. Now its time to clean up the residual effects. You are not alone.
Hope this helps in some small way.
