help.....

Alright I need some help ladies. I've always had this problem. I shave my vag and it's fine when I get out of the shower and a day later it's like this. I'm guessing it's razor burn. there's little white bumps but nothing ever comes out and they hurt like hell when popped! especially when its from my clothes. If it is razor burn what can I do to make that not happen? I've tried to shave with my hair like shaving down instead of towards me. But that never gets my hair. I've been thinking about those electric razors that you bring in the shower with you. Has anyone used them? thanks in advance
