Shaving between the cheeks!!!

I seriously want tips on shaving my ass. Any tips, besides the BS I will appreciate. I'm not considering wax!!! No even thinking about it. How do you control the itching?? Do you use a razor?? Tips.. I love doing it doggie style and my boyfriend wants to turn the lights on sometimes. I definitely don't want to turn him off by having a hairy crack. Thank you ladies in advance. If you think this is too silly to bother then don't bother, Don't need your negativity ladies.. Thanks again!
