Well I have problems reaching the desired area bec of my gut. So I can sympathize totally...& sucking my gut in??? Bahaha! Doesn’t do a thing. Cores are for apples!

I think you need to figure out what area you want done. Bikini line? Brazilian? The back door?
Then figure out when the last time it had attention & figure if it’s been awhile you might get a breakout. I know that with regular maintenance I don’t break out anymore.
I’ve had waxing of everything between my legs a couple of times. I enjoy pain & the labia area wasn’t too bad. But the roof of the clitoris brought tears to my eyes! An oh mother of god! Hot pain. Yikes. Butt, no problem.
What I didn’t like was the contract I was usually asked to keep. That I wouldn’t shave for 4-5 wks until the next waxing. I understand it’s beneficial for maximizing the effect, but if I wanted to do a quick trim before....nope. So I went back to my blind method.
Now if you’re really concerned what it looks like down there....some cameras have a timer on them...know what I mean?.....& selfie sticks r cheap now.

PS
Have any very good friends that could lend a hand???
