I used to tweeze that area before getting my first epilator.... So i have gotten used to the pain that tweezing caused.... Later after i bought my epilator just 1 year ago, i began to epilate....
1st time was rather painful, coz its like multiple tweezers at 1 go, so i had to epilate really slowly, small parts at a time.... But i soon got used to it n i dont feel any pain now, if the length is not too long ofcoz.... And i like the convenience n how fast the job gets done, rather than tweezing one by one and getting a neck/back ache later.... Haha....
Its better to get those epilator which can get wet tho.... Imo, its less painful than dry epilate....
Hope this helps you
