Yes. But there is no way would want to pollenate all of your females. If you were completely to pollenate one branch of one female, you would find yourselves swimming in seeds already. If you completely pollenated say five females, you would likely end up with thousands upon thousands of seeds. It's nice to make a small seed stock by crossing your best pheno's, but in most situations you're better off using clones. Seems complicated at first but it works out to be easier than dealing with the stress of selective pollenatiion. Check out this thread though:

That should give you some good info on these subjects. Finally, I didn't mean to suggest earlier that you should shy away from attempting to breed you best plants. I just think that if you're new to growing, you'll likely have enough stress and problems (most will be more minor than they seem, in my experience) without worrying about accidentally letting your whole crop go to seed. Do a few grows where you try to get the best sinsemilla bud you can with a small number of plants, then worry about making seeds. I'd even suggest shelling out the money for feminized seeds and practicing cloning before getting into breeding. It's hard to fully realize how much easier fem seeds make everything until you go with reg seeds when you want all females. You end up wasting so much time and money on soil, pots, space, light, etc. for male plants that the extra money spent on feminized seeds quickly becomes worth it. But it's up to you.
P.S. don't buy fem seeds every time you want to grow though, unless you love giving money to seed banks. just buy one fem. pack for each strain you want to try out, and make clones of your best plants.
