I went to the dentist and realized one of the procedures turns me on
Is there a reason they turn you on?
Yes, I enjoy having my teeth scraped.
It's not normal to get turned on by dental procedures. You should seek professional help about this.
It's fine, It's not like I'm hurting anyone and I've always enjoyed it.
Usually people do not enjoy dental procedures so this is strange. It could be harmful for your own body if you get fixated with it. I suggest you to talk about it with someone professional.
