Postpartum sexuality?

Okay so I know the recommended wait after birth before having sex is 6 weeks but I’m 4 weeks pp and going crazy. I lost all desire for sex while I was pregnant but it hit me like a truck once the baby was out.

I’m just wondering if waiting the 6 weeks is a very important thing? Is it okay to do non-penetrative stuff? If so, any suggestion on how to make the best out of that? 😅 haha

Also what about masturbation? Non-penetrative?
