When/If Sex is Okay During Reboot

Hey guys. I am 16 years old and I had been watching porn for 4 years. I am on an 8-day-streak, but I recently got an SO, and she is fully aware of this, even willing to go the whole 90 days. But I don't want to have her do that if it's not altogether necessary. I know there have been many answers to questions such as this, but not so many for someone as young as me. I don't know what still applies, considering my brain is still developing and I haven't been doing PMO as long. I have not experienced any sort of PIED but I have had some desensitization. I am wondering when sex is okay/if sex is okay for the reboot right now assuming I am not fantasizing during it and can achieve orgasm while fully in the moment, focusing on her. I know that it will affect the reboot no matter what, but assuming I don't have to fantasize and it's vanilla sex, I'm hoping that it would be at least moderately okay, even if the reboot takes longer. I also know of the Chaser Effect, but I believe I will be strong enough to handle it. Any help is appreciated, and I can answer any follow-up questions. Thanks.
