Overcome fantasies( incest, cuckold etc)

Our brain some time got damge by these fantasies (incest, cuckold etc) we dont see anything… To overcome these things we have delete all the sources like Instagram, telegram etc… So that we can maintain our streak long and eradicate all these from minds… Bcoz our dopamine level got so high when we think like that, nd we got addicted then… Unable to concentrate and focus on work and studies.
