I have two goldfish. I suspect they may be of either sex, but I'm not totally sure. Please help me out.

Firstly, sexing young and juvenile goldfish is virtually impossible, you have to wait until the fish reach breeding age (usually one year old).
Secondly, sexing adult goldfish out of the breeding season is difficult, because the sexually distinguishing features only develop during the breeding season (in the spring time). That said, females may be deeper in the body than males.
During the breeding season, the following physical features develop:
males develop breeding tubercles (white pimples) on the gill covers and on the leading edge of the pectoral fins
females develop a deeper body as they fill with roe (eggs), and have a larger vent (just before the anal fin) than the males

The males, as they mature, will develop small white tubercules on their gill covers. The females do not. Do not confuse these white tubercules with the parasitic infestation called ich which looks like salt stuck to the fish.
Also, when viewed from above, the females are wider and heavier than the males.

Male goldfish always dress in blue, the females in pink.

I'm not sure, but I think they are all asexual. They are all the same sex, but one changes when required to reproduce.
