^ Lol don't worry, I think I spotted a grey or two last time I bothered to push my preggo belly in and get a look-see down there!!
As far as shaving 'underneath the curtains', I find it easiest to just squat down in the shower and go for it... I've been doing it for so long now that I can go solely by feel, but a mirror might come in handy. You can shave from back-to-front the way you would do the top bits, then stick your hand down behind you and under your leg and make like you're wiping your backside, iykwim??

I'm very wary of that hair removal cream... I don't have sensitive skin but I remember my nanna used to use it on her upper lip, the stuff smelled so incredibly vile I just KNEW it couldn't be good to slather on delicate parts!
