Is it Ok to make love with better half during reboot

Whatever is and is not allowed is entirely up to your own standard, some folks have lower standards for themselves, others have higher.
It all depends on what kid of adverse effects you feel from PMO, and wether having sex worsens any of those problems.

If you want to still make love to your wife, but wish to retain semen I would look into Karreza, or if you don't mind throwing in a bunch of spiritual idea's, tantra, though your wife would have to be open to those idea's too.

Here's a site with loads of info into karreza, it's basically lovemaking with the idea that orgasm isn't the goal, and that you don't orient yourself towards this pleasure, and are instead just there, in the moment, with your partner to love one another and be intimate.
