I work for Planned Parenthood in Cincinnati, and just last night met someone who is planning a smiliar week at the University of Cincinnati - but she works for Pure Romance. They are headquartered in Cinci, which is probably why they're involved, but I'm sure there are consultants in your area who might be willing to donate some products or demonstrations in exchange for some publicity? If you would like the contact info of the person I know, shoot me an email: volunteers@ppswo.org.
Good luck!

I have done several d.i.y gynecology stuff and that can be a lot of fun. You can have an anatomy quiz, menstrual charts that help you learn more about your cycle, info on speculums and information on Alternative Menstrual Products.

I think it is important to encourage people to be familiar with their bodies so they know what their "normal" is so it is easier to identify the abnormal.

I don't know as much about sexual health for male or trans bodies, but that could be other useful information.
