Connection timeout on startup+parental controls?

I've been having a problem with my computer. Whenever I log into my account and try to start the internet, it takes a few minutes for the internet to work; if I try to access a webpage prior to this indefinite span of time, the internet ends up timing out. The same thing happens with parental controls; everytime an HTTPS website is approved, it takes a few minutes for the internet to start working again. I am currently running OSX 10.9, if it heps clarify things. This problem only appears to be happening on my account; the internet works fine on my parents' accounts. Help?
