Confused. Need some insight

Hello,

I am a 24 year old male. I was diagnosed with ocd around the age of 12. When I was younger 12-20 years old, I had a fascination with women in thongs (underwear). I would solely search this out when looking at porn as a young man. I believe it was bordering on a fetish. Around 20 years of age I developed p ocd after getting over harm ocd. From this point until now (4 years) I became obsessed with researching on paraphilias. I constantly browsed this forum in the paraphilias section and kept looking for reassurance. I cannot get over this theme of ocd because my mind tells me that I already have a paraphilia ( fetish) and that I am already some kind of pervert . I can't stop obsessing that if I already have a fetish what if it switches to another paraphilia like pedophilia and this scares the hell out of me. Prior to the age of 20 I never even thought of children. I kind of knew that I never wanted kids because of this disorder (ocd) because it is hard enough as it is taking care of myself through relapses. However, since getting stuck on p ocd I have constantly been avoiding kids and get scared in public if I see kids . the whole situation is really hard and I'm not sure how I'll ever get over this theme

What are the chances that you can develop another paraphilia if you already have one ?
