Do I have OCD or mild hypochondriasis?

Hello,

I am 19 years old and I watched a lot of pornography over the summer and I feel that gave rice to sexually intrusive thoughts about family, strangers, etc. For a lot of days I felt anxious over these thoughts, but I am now settled as I realized that these thoughts were meaningless. Basically, I was able to push myself out of the anxiety. Moreover, when I had these thoughts and anxiety, my life was not impacted at all as I was still doing whatever I was doing before the thoughts and it wasn't impacting my life negatively. However, there was some slight distress associated to those thoughts. 6 years ago, as a 13 year old, I had a similar bout of intrusive thoughts and anxiety following some intense hardcore porn viewing, but that also subsided on its own, and it never bothered me. I recently googled intrusive thoughts and I found out it is OCD. But I took the Yale-Brown OCD test online and it said my score was 4 or 5 - i.e. little or no OCD. So my question is, dear forum members, do you think I am someone that is just by nature a little obsessive or do you think I have OCD and I need to go see a therapist? The reason I am asking for help here is because getting a therapist in my country is a big investment and I want to know if I really need one.
Moreover, my father has hypochondriasis, and so I am wondering if all of this thinking that I have OCD is a hypochondriasis symptom - last year I was obsessed with the thought that I may be going bald when I was not.

So, do you think I have OCD?
