Keyword Questions, Traffic, and Prostate Orgasms

Prostate orgasm's - have you had one? Rhetorical

I'm using SEM rush and trying to learn to understand traffic and keywords. A lot of the keywords I want my site to be on the first page for, it already is. So, should I work to keep those at the top or once they are, do I just let them ride? So let's say the keyword is "cuckold", should I continue to write articles on other sites which are cuckold related to KEEP it at the top or does this hurt me? I don't think it should hurt, but good to ask if it can end up screwing me up.

Next, when I want to go for a broader search term the competition isn't even competition for sales. It's freeking wiki, and articles on how to do this or how to do that. Not even a competing site selling what I am on the first page from what I can tell. How the heck do you compete with wiki and cosmopolitan mainstream sites when you're selling an adult product?

This traffic stuff is getting a LEETLE addicting. I layed in bed this morning on this snowy day thinking.....

I can't wait to get up and check to see how I improved. My beautiful sleep as I know it is fucked. Is this how SEO traffic stuff is....forever?
