Warm water, preferably new or still sharp razor, shave in the correct way considering hairgrowth, stretch the skin with other hand, use a lot of foam... and be slow and careful. It's once a week thing for me, and I have never cut myself yet.
Try 2inch medical tape (micropore), or kinesiology tape, .. I suggest using some piece of toilet paper or towel/wipes to prevent some of direct contact to skin.
