Hi, I know this is very late (10 yrs later) but I pretty much was the same age when this problem started happening to me. I am 20 years old now and ever since shortly after I turned 19 I feel like I can't be around kids , animals, family, etc without being paranoid of lusting. I feel like I am so paranoid of lusting that I feel like I am lusting but deep down I know it is discusting and I would never want to act on those thoughts.
Was your situation by chance handled? Is it possible to ever date/marry and have kids after experiencing these thoughts?
I feel like my life is falling apart and is worthless because of this.
