Waxing...... Brazilian style!

Has anyone got any tips/experiences with waxing?

I tried it the beginning of last year, I only got 2 rounds done but kept getting really bad ingrown hairs & was like $90 for it to be smooth for 4 days MAX & they told me I had to grow for 6 weeks.. didn’t seem worth it.. wanting to do it again to give my man the sexy smoothness.. but wondering if it would be the same as last time & if it’s even worth it?
