I have done my own brazilian for years at home. Have to do it about once a month. But after 2 attempts in the last couple of weeks with no success cause I could no longer see my whoohoo I decided to got to my local beautician. Very embarressed as I didn't know what to expect. But the lady was lovely and did it under 5 minutes (or it felt like that anyway). I still wore knickers, just loose ones or a g-string is good. They just do one side at a time so they don't really go near the wettest bit. I was surprised how comfortable she made me feel. And it feels so much better now. Might not even bother doing myself anymore after bump is born. just quicker and easier to have them do it.
Go for it, oh and yes when the hair does grow back for a few days its very itchy but after that its fine. In fact the more often you do it then lesser hair comes back each time.
