Is it best to have free porn site or pay site

[Doyouvideos]

I've been making my site free for about a week now, the thing is with a free site my ranking gets lower and I get more clicks on my juicyads that's good, but with a black site not too many advertisers want to buy ads, I look at other black sites they get way more traffic than I do, they have tons of ads on their site, and no advertiser from Juicy ads is buying space on their site, They charge a lot but I don't blame them, they have the traffic to charge a lot......I don't want a free site if it's not gonna pay off from advertisers buying space on my site..........Should I switch back to a pay site or stick to making my content free, what is better for my wallet?
