Bikini area shaving help?

I started shaving my bikini area last year as for the need, but more so for the comfort when wearing a swim suit. I soon realized though that I have extremely sensitive skin. I use sensitive skin shaving cream and lotion and lotion razors with a god blade. I know I am shaving the right way to, so it just comes down to sensitive skin. Plus I get lots of red bumps and ingrown hairs and my bikini line appears very rough, which can all be seen when I wear a swimsuit. Embarrassing! Anyway waxing and lazer treatment are out of the equation, so does anyone have any recommendations on how to get rid of the bumps, especially with use of creams? I have heard aloe vera works, anyone have experience there/with it? And also does anyone know if the Quattro for women bikini shaver helps with the bumps and all? And lastly I have a happy trail that just appeared and is an obnoxious grey/black. Everyone says not to shave it, which I am not going to and since waxing is out of the question, does anyone know how well bleaching works? Does it leave this trail on your belly that is extra blonde/noticeable, or does it blend in pretty well? I just want it so its not so in your face. Also any recommendations on bleach brands? Thanks for all your help. Also I will be rewarding extra points to the best answer so give me your best. :)
