If you're going to be taking submits, then yes, I'd advise getting a script to run things. (if it was just a hub with your sites, then I'd do it by hand)
I use Link Admin -

As far as categories, I can think of a lot of them for lesbians:
toys
blonde
brunettes
amateur
teen
mature
strap on
ethnic (asian, latina, evony, etc)
petite
the list goes on.......
