How do you know you're healed?

At what point in the recovery process should you start pursuing women and having sex?

Should you wait until you feel totally healed? How do you know you're ready?

Or do you need a partner as part of the recovery process to help you heal and rewire your brain to healthy sex?

I've heard stories of guys falling back into a flatline after having sex. This suggests that they still need time to reboot.

How do you know you're ready for the real deal? Should you basically be feeling like a horny teen again? Is that realistic for older guys in their late 20s/30s?
