Am I supposed to give up sex during reboot?

You can choose whether or not to give up sex. Hard mode (no sex) is usually recommended as the fastest way to treat sexual dysfunction. I have continued to have regular sex with my wife since my problems weren't severe and I don't want to deny her pleasure. Since you mentioned losing erections you may benefit from hard mode but it is your choice.

 

If your counter is for no P and no M, you do not have to reset for O, unless you are taking yourself to O.
Going hard mode, no P, no M, and no O, is more difficult, but seems to give faster, better, results. A 30 day break from all sex might make a new man out of you. A complete reboot will probably take 90 days, but 30 days may get you to the place that you will enjoy more than her hand and mouth. It is a sacrifice, but most anything of value requires sacrifice.
For 30 days just dream about enjoying it together. Then see if you do.
