Whether you believe what I'm saying is up to you, but here's my take on it, which I'm sharing because I can relate to you on the bullying and weird kinks/fetishes/double life bit.
As already said, a functioning adult worth their salt at worst are just going to rib you a little. As long as you can take the banter and understand that most adults aren't going to bully you to the point of feeling excluded then you'll be fine in most workplaces and just everyday life like shopping for food or going to the movies. That's the reason why I pointed out that the adult world is nothing like school. Because it isn't. I have an annoying stutter at times and only the shittiest people actually mock me for it. I tend to be awkward as well and people don't bully me for that either.
Most people will put in the work to be respectful, understanding, and tolerant. All you have to do is put in the work to be the same of them.
As far as weird fetishes, attractions, etc, why is it anyone's business but yours? I fap to futas, monster girls, and girls sticking their fingers/tongue in foreskin and yet, this never has to come up in normal conversations. I don't just talk about my obsession with sex toys for that matter either. And knowing how people are, I just assume people have weird kinks and hobbies too. Maybe my manager at work is really into scat play but if he does, he does a good job at hiding it.
Only people I see who get rejected are those who too proudly discuss their more TMI parts of themselves to anyone. I work with such a person, she just told me about how she loves gay guys making out and how she's an asexual, and how she loves the NSFW nature of the Undertale fandom, and once announced that she had to shove a tampon up her snatch.
I don't know, I know you said that you don't like being a pedophile, but just don't make your kinks/sexual attractions into your identity? Just don't be that guy in pic related.
