I have the same small maori forearm 'sleeve' and the one memorial on my calf. For piercings I have my lobes to 00g lobes (about 9mm) and 14g labret. I may stretch the lobes to 1/2 inch, but I'm not sure if I'll go beyond, depends on what I'm doing in life at the time. I'm also trying to get the labret to possibly 12 or 10g just so it heals better and it won't close so easily if I ever have to take it out temporarily.. I want more of both and have plans for several tattoos and a few piercings but funds for neither at the moment.
My gf though is covered with holes.. 19mm first lobes, 10g second lobes (used to have double tunnels), 2 further holes up each side, a tragus on one side, both nostrils, a septum (not a huge fan of it but whatever), labret, eyebrow, navel, and 2 that are just for me

, for a total of 17. 3 tats as well.
