"Sexual trauma"
is generally associated with sexual assault. This does not invalidate your feelings in any way, but perhaps it is not the best term(?)
Do you think you would characterize your behavior as
sexual addiction?
If so (or even if not), you are definitely not alone. Much information and resources for help can be found by googling:
women and sexual addiction (including
some of the related searches at the bottom of the first page).
Even if any of the above
doesn't relate to you, there may be something there, or mentioned, that may help you describe your feelings, or put your particular situation into words. There may also be resources to help you find other women who
can relate.
