Some quick ways to get Traffic (apart from SEO, which will need time):
1) Forums (becareful not to spam)
2) Social Networking (facebook doesn't allow porn, if posted, poster account wil be banned after sometime)
3) Link exchange (just make sure your site is not overwhelmed with the links to other site)
4) Post unique content (photo/video) to popular/well known porn site with your website name on them.
Finally:
5) Join
Plugrush and build plug. That way you will recieve some traffic. I remember at some point I was having 1500% return from
Plugrush. I sent them 53 and got 780 in return.
