I had sex yesterday, is that relapsing?

If it was with it was more romantic than lust then you good

Tae keep in mind that a lot of people here are Christian’s and from other religions too. It is up to you what you consider a relapse. As long as it doesn’t fall below the baseline, which is watching porn and masturbating with it. Sex isn’t watching porn.

i felt very in control

That’s healing? As a young man, it is sinning if it’s not your wife, but this is life. You can try to live beyond this life, it’s hard and will take a lot of self control, or you can live this life and heal from porn by behaving in responsible exercises of your masculinity. They don’t have to be sex, they have to make you proud of who God made you.

Depends on your perspective and goals. From my personal perspective, if you downloaded this app to gain better self control over your sexual behavior and you felt out of control yes. Additionally, my personal belief is that it’s sinful if it’s not with your spouse. That’s my two cents.

I would think not
