Shaving tips?

I have really sensitive skin, and I'm PRONE to razor bumps. I use sensitive skin razors and shaving cream. I use conditioner on my bikini area, and it's working to prevent it a bit, but I still can't put clothes on after, I have to wait or I get them really bad. (I think it's because of friction) (I don't use conditioner on my legs/under arms because my family uses so much of it) I wait to put lotion on for a few hours which also helps prevent them. (I put on lotion every where every night) I've always had this problem and would like it to go away. HELP!!!
