Here is what is going to happen (trust me). You will buy the domain and then put some tube script up and then start buying traffic to feed it. Once you get on Pornhub's radar they will come calling and take the domain from you (and quite honestly i feel they should). Back in the old days the Hun used to offer $100 to anyone that bought a domain for adult with the likeliness "hun" in it. If you didn't sell it then you would most likely pay the price later LOL!
Anyways it's not worth the effort and bullshit. Just register another domain and build it up, that way you won't run into issues later on.
Just my 2 cents obv.
