That is how the hounders respond--disfellowship first and ask questions later. Your "problem with sexuality" means precisely nothing. It could merely be a masturbation issue. Or, you could be gay or bisexual without doing anything--since when can you get disfellowshipped for merely being attracted to a same-sex person? Or, it could be that you wish to date a worldly person. At this point, there are simply too many things that it "could be" for them to jump to conclusions.
And, chances are good that the "problem with sexuality" is really a problem with the religion or the hounders. You are attracted to someone, or a category of people (usually other men) that carries shame and guilt within the religion. So what. If the "problem with sexuality" is merely you wish to date a worldly person, it is most definitely a problem with the religion. Yet, the hounders are going to make more out of it than it really is--as if you already committed fornication or homosexuality. And they are going to act accordingly.
However, when pedophiles get away with silencing their victims, it is usually "slander" that they use as a threat. A pedophile needs to witnesses to the event "or it never happened". They never afford homosexuals the same benefit of the doubt--either two people had to witness the event or it never happened. Regular fornication is also not viewed like that--you are looking at a possible slander situation. They almost never disfellowship people for falsely blowing in people with a "problem with sexuality" as if for fornication--yet, if you blow in someone for molesting a child, you can get disfellowshipped on "slander".
