Aside from the sexual comments and sex toy prior to your complaint, it sounds like the sexual conduct stopped after you made your complaint. If your expectation of something "being done" about it is that your employer must take disciplinary action, such as termination, you are expecting more than the law requires. The employer need only take action that stops the sexual harassment.
Your problem seems to be retaliation for making the complaint. Does your employer have someone in charge of human resources or personnel? Most discrimination and harassment policies have complaint procedures that encourage employees to bring their complaints to HR, because HR is in a position to do something about it. Make your complaint to HR, and be prepared to provide specific details of the dates and times of the retailiation, witnesses to the retaliation, and how he has encouraged your co-workers to turn on you. Hopefully, you have a work record that comes close to having a history of walking on water. If your history is blemished with personality conflicts and incidents of insubordination, be prepared for HR to come back with an explanation that says you are the problem.
Your next step at that point would be to file a charge of discrimination and retaliation with the EEOC.
