Musician Experienced in Teaching Drums and Composition
You're not alone there. Many non-drummer composers struggle writing for drums. Your biggest resource will be to listen to similar styles of music and try to figure out what the drums are doing in those songs. In addition to that, I highly recommend you try to get yourself behind a kit at least a few times. Ask a friend if you can just jam on their kit or, even better, take a few lessons. This will be better than anything else in giving you an understanding of the mechanical limitations of the instrument.
The biggest error I've noticed with composers who use VST's (I'm assuming you compose with a seqeuncer/DAW) is writing drum parts that are physically impossible to play. Keep in mind, a drummer only has 2 feet and 2 hands. That maximum amount of sounds you can hear at once is 4, 2 of which will be the kick and high hat foot. While your VST can do any number of impossible things, if you keep your parts within the bounds of physical limitation, it will make it seems like your parts are being played by a real person.
