First down there shave

Okay so I bought one of those bikini trimmers and took off the gaurd and trimmed so there is only stubble. My skin was getting irritated from just that so I though I'd leave it like that for the night and shave it smooth in the morning. So far it feels very weird. I'm thinking maybe because I'm not use to the feeling being my first time shaving down there. Any advice? I've read a lot online and that's helped but it's always good to hear from other people. Also is it normal for things to feel weird down there after a first shave?
