VIBRATOR!!

So. The past couple months (5) have been tough. For reasons I don't want to get into I have been unable to be in the same state as my fiance (this will continue for the next 2 months). So I decided since I can't be with him I needed a way to relieve some sexual tension. So... I bought a vibrator. Well it came in today. But I've never used one before. Any advice on how to use it, or techniques that will make it feel better? Or more intense?
