Hey buddy! No big deal! It's not embarrassing at all! It just takes some creativity, that's all. Using a 4 bladed razor near your pride and glory can seem extremely daunting. I use a few different things to help clean the place up.
First off, scissors. Don't chop your hot-dog off! haha.. but before you begin shaving, I highly recommmend trimming the area up. If you had a gigantic beard on your face, you wouldn't up and start shaving at the beard, you'd get no where! Depending on how hairy your jungle is, you may want to trim the place up before you go for the complete shaven look. It'll make things much easier to manage!
Secondly, shaving. I highly recommend using shaving cream if your going to use a razor, but if you're not comfortable just yet with your razor shaving skills, there are many alternatives, which I have personally used and will now list for you.
My wife has one of those little hair removal pens that are meant to be used on eye brows and upper lips. They sell them at Walgreens for like 14.99, they cut remarkably well, and did wonders on me. They have a guard, so it's practically impossible to cut yourself with it. Granted, if you do decide to use your womans eye brow/upper lip shaver, get the pubes out, she might get really upset that you were using that down there and now she has it on her upper lip. (speaking from personal opinion). I ended up buying her a new one and keeping her old one.
Electric razor. There are a many different kinds of electric, but if you go this route, make sure you have a very GOOD razor, not a cheapy that gets stuck and pulls hairs, your testicles will never forgive you for using a cheap razor and it catching on your hairs. It hurts, and I don't really recommend them. Wahl makes an excellent electric razor for facial hair trimming and hair cutting. I think they sell for 20-30 bucks. Not terrible, but definately not a long lasting razor. I'd keep it for a year tops before buying another one, since over time, the blade has gotten slightly dull.
The old fashion razor. IF you do decide to go with a regular razor, there are a few things to remember. When you shave your face or neck, your skin is full, it's not wrinkly and saggy like a sack. Try squeezing the sack and making various shapes like the Snail or the brain, Even the batwing has a use here. (The key is to smooth your testicles so there is no wrinkles by squeezing a part and making it "full" and tight so there is no accdients. Almost like a brain) Or stretching it out (like a bat wing). A good sharp razor, lots of carefulness, and a good shaving cream that provides protection and lubrication for the blade against your skin is important.
I wish you luck in your hair removal adventure. I absolutely have to trim, I literally grow sideburns, and stray hairs in your wife's throat can ruin the mood =\
