<human>: Could you distill the essence of the text into 1-3 sentences?

I have a pretty good friend that I'm slowly finding myself attracted to and I don't like it. She's obviously a really nice girl but much to young for me. I know she likes older men. Also I think she's tried to drop hints but I'm an idiot when it comes to that stuff so always assume I am wrong. 

Lately though my mind wanders and I consider it but I know that it would ruin a great friendship. Thankfully at 39 its a lot easier for me to keep my dick under control. That said I don't like thinking that about her. How do you get rid of that?

added for rules: we've been friends about 18 monthes
<bot>: OP has a much younger friend and starting to be attracted to her and he doesn't like it. How does he get rid of that attraction to her?
