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.
After reading what people have posted on this topic, I think I have came to the conclusion that I have OCD as well. I havent necessarily been strungling with unwanted sexual thoughts all my life but for sure unwanted thoughts. They just don't go away for a really long time and I feel like once i get rid of one unwanted thought that makes me anxious/miserable, it gets replaced with another one. The first time I started experiencing unwanted sexual thoughts I would have to say was during adolescence. From then to now I have been paranoid of being homosexual and it has really killed my confidence. However, I think my unwanted sexual thoughts have gotten much worst for the past year. I am extremely paranoid of liking animals, children and family in a sexual way. It has gotten to the point that I am so paranoid of lusting that I feel like I am lusting. I don't know what to do about this...I feel like a terrible person and I don't think I will ever be happy because I feel like I wont be able to ever date or marry anyone because of this.
