Brazilian wax

I really want to try it but I'm scared of how badly it might hurt. I know everyone has a different pain tolerance but honesty I don't think I have a particularly high or low. My bf and I are getting pretty serious and I just want to feel sexy for my first time having sex. Also, does it get irritated easily after getting it waxed for the first time? And when they do the wax they do everything including like the inside of my thighs right? I kinda want to do my lower legs too, but I'm not as worried about the pain there Bc I think we can all agree our vaginas are a lot more sensitive lol
