Welcome to
GPC!
I ditto what everyone else has said and am glad you have decided not to breed. Also, if you do get a friend, another male will be fine, or you can neuter Brother Pig and get a female. But whatever you do, ADOPT don't buy.
Check out Ly&pigs diet and nutrition chart so that you can give the right amount of veggies everyday. Make sure they have good quality hay, Kleenmamas and Oxbow are the best. The same goes for their pellets. Oxbow, Kleenmamas, sweet meadow, and Mazuri are the best. No Kaytee, no Hartz, no Zupreem. You can get Oxbow at PetSmart, but I personally frown upon buying such a wonderful product from such an awful place. Try and find it at a feed store that doesn't sell animals instead, or buy it online. Buying online in bulk is cheaper anyway, even WITH shipping.
