I shave about every 3 days using "Dove" soap...it only takes 2 or 3 minutes to do my testicles, the shaft, and the first couple of inches of my thighs. I find it helps to at least be semi-hard and since I'm (most guys are) like that several times a day, it's not a problem.
I have had laser hair removal on my pubic and underarms. It was expensive, a bit painful and at the time could only be effective on certain skin types.
That was over 10 years ago and the state of the art has advanced greatly since then. Also the price for having it done is only a fraction of what I paid. Both my daughters want it done. and I will have it for them. Oldest who is 16 is old enough now and will be first. My 12 yo is still a bit young for it.
As it stands now, I help the girls with their shaving. before my laser treatment, I had my sister assist. For those still shaving or using a depilitory, the contents of a vitamin E Jelcap topically applied works wonders on the effected area
