I struggle with intrusive sexual thoughts. I have a girlfriend. These thoughts will be about other girls, the thoughts can range from sexual acts to wanting them to be my girlfriend and this thought specifically always seems true. The way I overcome all of these thoughts by telling my girlfriend all of them. If I don't tell her they will stick in my head. The thoughts will go when i tell her. When I tell her she is obviously upset by the things I tell her. I need a way of not telling her and breaking the cycle.
