I have used an epilator all over my body except my face, for years. They work pretty good and the hair comes back in thinner as the roots a damaged every time you yank them out. I'll admit, the first time hurts like heck and you may want to consider a few stiff drinks and or doing small sections at a time until it's done. I'd also recommend shaving first then epilating the hairs as they come in so that you are not pulling so many hairs per square inch.
After the you get through the first time, it really doesn't hurt at all. If you are still full of T and your hair is coarse, you are more likely to have issues with little bumps and ingrown hairs. I work every day as a guy and NO ONE has ever asked about my hairless arms and I work in a industrial/ emergency response business around all sorts of white and blue collar guys.
I just wanted to mention that fact since it seams so many cd/ts that are in guy mode seem afraid to remove hair like it's just going to set off all kinds of ->-bleeped-<- alarms or something. My wife likes me smooth and only complains if I get "pokey" as in whiskers. I wish I could tell her everything but I know it wouldn't go well. She is open minded to gay/tg sort of stuff but not when it comes to her husband.
