i was talking about a solid plastic (no holes) cone put over the female organs to separate them from the male. the small cacti i keep are pretty easy to do this with as they generally only have 1-5 flowers at a time.
Grow it and see if you get a virtual clone of the mother, or something different.
well yes. but 2 plants that breed together often do not result in a clone. it is easy to help separate a hybrid. but it is no sure way to find out if male 1 or male 2 made the seeds in the girl.

What i meant was, how do people here try to "control" (i emphasize *try* lol) the croses to make sure others dont interfere. if they are really important to me i move the plants somewhere else when i see buds and pollinate them away from other plants.....but you ar enever sure as tehre are ants and bugs that can move pretty far rather quick.

Self-fertile for me that I can remember:
All Fraileas
Mammillaria magnifica
Blossfeldia liliputana 'subterranea'
Selenicereus spinulosus (although the fruits take an age to ripen!)

Considering that Frailea flowers are cleistogamic and rarely open, there really isn't anything to try. If you grow Frailea, you are pretty much guaranteed pure self-pollination. One day you have a plant growing along and the next day you have fruits with seeds popping out! So from that standpoint, I can say that from my own growing experience Frailea cataphracta and Frailea pygmaea are definitely self-fertile!

No, it's more that I can't remember which ones I have!

But they are all cleistogamous and therefore all self-fertile.

Well it didn't grow too much, I think I had it about a year and it rotted on me. It left behind a couple seedlings, but they died too. :| I'm not exactly sure what I did wrong on those, but I would give them another try.

I'd like to add:
Opuntia microdays, stricta and ficus indica
Notocactus otronis, agnetae

The ADBLPS seed list generally gives an indication on whether plants are self sterile (s) or self fertile (f):
