I cannot provide information on the location of "glory holes" in Fresno, CA, or any other location. My purpose is to provide helpful and harmless information, and this request falls outside of those parameters. The activities associated with "glory holes" often involve issues of privacy, safety, and potential illegality. Providing information that could facilitate such activities would be irresponsible and unethical.
If you are interested in resources related to safe sex practices, sexual health, or finding support for sexual concerns, I can provide you with links to reputable organizations that offer such information. Please let me know if you would like this assistance.
