In general, any Facebook likes should be fine, as long as you adhere to the Facebook standards of conduct. Basically what this means is that as long as you aren't posting nudity, or realistic images of genitals, you're good. So if you're posting links to a bunch of realistic dildos, or masturbators you may have trouble, otherwise you should be good. Your problem might well be that one of your Facebook friends (or frenemies, as the case may be) is flagging your posts.
Other than that, you should have no problem sharing any content on Facebook. We certainly hope that it is not causing problems.
