I learned it. Do you have a tom rhythm in mind from a particular song? Then listen and, if possible, watch the video to see what the drummer is doing, then practice the bejeebus out of it. You could also ask your teacher to break the pattern down for you. Often these tom rhythms are simple single stroke stickings, and the only complexity is the subdivisions and the physicality of moving hands to different toms.
Larry mentioned the Bo Diddley beat. Many common tom rhythms are variations on this timeless pattern, and that is an excellent place to begin. If you aren't familiar with it, it's basically a 3:2 clave (ba baaa ba, bum bum). Check it out here:

Comp that a little bit on a single drum with one hand, then with two. Then start filling in other places between the clave, or switch notes between the drums. For example, you could place the first three notes of the clave on three descending toms, then the last two on the snare; or backwards, while keeping steady four on the kick. Maybe you are ringing out eighths on the ride cymbal bell while playing the clave with the left hand as described above. Maybe the right hand is playing those eighths on the floor tom. See where I'm coming from?
Larry is correct in that if you are not feeling it, you need to practice it for feel. Best to start simply, as I said, with one drum, even with one hand. Make that clave feel natural. Play along to a song that features the Bo Diddley, if possible. I personally find it hard to get all the feel without music to play along with, whether in my headset or with other musicians. Then practice some more. Remember what I mentioned before, if you are transitioning out of something on hats or ride into the tom piece, feel it, don't tense up "omigod omigod hereitcomes hereitcomes ogod ogod" -- best recipe for a train wreck ever. Practice helps with that.
