I don't suggest depilatory cream for your private parts. Nasty stuff and as DLD stated, you can burn yourself with that stuff! I've tried some depilatory creams on my body and they've all been a let down. My shaving is done in 1 -2 minutes. I don't want to let some damn cream sit on my body and then try, ohh, it hasn't worked yet, let's wait more. Useless gunk in my opinion.
Shaving, fastest and easiest. Plucking, takes a lot of time, a bit more lasting results. Waxing could be one option, but it's pretty harsh on the skin my opinion. Sugaring might be slightly better option compared to waxing.
