Rough anal is definitely a huge turn on and can be awesome with a willing partner and the proper preparation.

Lube, lube, and more lube!

If you have the opportunity to prepare beforehand, use a moderately sized butt plug for awhile before the main event. Put some lube into a squeeze bottle that has a small nozzle of some sort that you can insert into yourself and squeeze a good amount of lube up inside so it's there and ready for the fun.

Use a good silicone based lube, water based dries out and gets sticky very quickly. Eros is one of many good brands.

Be careful using silicone lube with silicone toys. Check the labels to make sure they are compatible, if they are not, the lube can melt or deform the toys which is not fun at all especially if they are inside you at the time.

Have fun!
