There is nothing unhealthy with humiliation fantasies, nor with pretty much any other fantasy. Fantasies are an escape from the world, sort of a short mental holiday. People fantasize about all sorts of things -humiliation, spankings, extreme bondage, forced sex, castration, you name it. None of these are, in and of themselves, unhealthy.
Unhealthiness comes in when your fantasies begin to rule your life. Spending time fantasizing when you should be doing other things like work or school is not healthy. Becoming fixated on a fantasy to the exclusion of other relationships is not healthy. Acting out fantasies in ways that cause you or others harm is not healthy.
The key here is that it's your reaction to the fantasy that causes it to be unhealthy. If a fantasy gives you feelings of guilt, then that's something you need to work through to return the fantasy to the healthy side of things.
In this case, I'm going to take a guess that some of your posts here are intended to share with us some of your fantasies, and thus experiencing some of the humiliation you keep fantasizing about. While that's not necessarily unhealthy, you might find it more productive to write some of your fantasies and post them online. That will let you work through some of your feelings, while still giving you the enjoyment you seek by sharing your fantasies.
I would also suggest that you quit consulting your family about what is healthy versus unhealthy to fantasize about. Most people are unlikely to get good advice from their family on that subject, because it's fundamentally counter to the sort of relationship that families create.
