+1 on this. I actually recommend 2-3 prior. There have been a few times I failed that rule and did it the night before an apt and cut myself. Depending on where that cut is it could dramatically increase your risk of an STD should one be present. One time I had a cut on the top below the base of the shaft and actually canceled the apt due to that (I didn't tell provider this just said an emergency came up). Better safe than sorry. Oh, and I been shaving/trimming body hair for near 40 years now before it was popular. I never liked the look on myself because I was always naturally patchy. Like who wants a couple random patches of chest hair, few girl prefers that, it isn't very manly. Better smooth if it doesn't grow in masculinely. And agree for BJ/RJ definitely necessary if you want best experience possible. It may not always be better experience, but it won't ever be worse.
