Hi, Ink,
Well, gosh, this all sounds like various forms of sexual harrassment. The fella who touched you inappropriatley at work should be reported.
As for the man who is mailing you pics of his groin, but worked with you in a previous job. If you feel you would be safe in doing so, report it too...either to his work or to the authorities. There is no way you should put up with this!
