domain name help

hi everyone so today i found a good domain name for a another tube site that i would like to buy but the only thing is the only way it is available is if i add xxx before the domain.
i checked google keyword and the keyword without adding xxx has over 100K monthly searches so was just wondering if it is worth it to buy it still ?

how much is it for sell?

i was looking and the domain is like 10.99 on godaddy but not sure if it is a good domain because of the xxx before it

You should analyze well the site without the xxx, do the site have quality? is the content good? how much years have the domain?, if the site without the xxx is bad, you have pretty good chances of rank better, even with the xxx behind.
