Is sexual triggers fine during NoFap period?

you will have to state your question more clearly

 

1. Are these sexual triggers causing you to relapse and engage in PMO? If not so far, have they done so previously?
2.Are you viewing these sexual triggers on purpose or unintentionally?
3.What are you goals? Are you looking to be completely free of the grasp viewing and MO’ing to porn and sexual stimuli completely or looking to be able to moderate it better?

ultimately it’s never a good idea to “diet” a bad habit. It keeps those pathways open rather than letting them go for more positive things to take their place. I’ll go ahead and give my stance that you should aim to lessen purposefully seeking out sexual stimuli because it’s something you yourself can control and improve upon. We’re not perfect so we may peek here and there but it is never advised, for it makes the recovery process more difficult than it already is.
If you’re worried about unintentional sexual triggers you come across, pay them no heed, don’t act upon them and keep moving forward. As long as you don’t put such an emphasis on them as you come across them, they begin to hold less power over you.
