When should I wax?? (Sex related)

Uhh okay lol
So this is really awkward for me to ask...
Me & my boyfriend are going to the city & going to a hotel after having date...to have sex, but I really want to wax my uh nether regions before then.
How many days before should I wax?? 
Like is it going to burn if I get waxed 3ish days before??
