Risky if you don't fully understand the ad policies and the right angles to use. In short, your product is for enhancement and not for contraception so it's not really eligible. The workaround is if you were to create ads focused around safe sex/contraceptives and then have your spray on the back-end - still risky unless you know what you are doing.
Non profit organizations tend to get away with more so don't copy them directly. I would suggest to visit some websites that are related to what you do and see if any of their retargeting ads show up in your feed. You can get away with a lot more with direct fan page posts vs sponsored ads so don't assume just because another page posted something that you can also post the same.
Lots of potential issues with sprays/FTC, people bitching about how your ads dont belong on Facebook, and so on so you'll need to address those issues.
