They all include Acting Out in one's addiction, and require a restart in sobriety AND Recovery dates.
Let’s look at some definitions.
Acting Out - Intentionally seeking out any erotic and sensual stimulus, even if "accidental"
at first. DEFINITE lines of acting out: Masturbation, Pornography, Infidelity, Emotional
infidelity, Inappropriate relationships with opposite sex, Chatting, Flirting,
Sex ad browsing, Forcing anyone to have sex (yes, even if it’s your own wife), & Massage brothels.
Pornography - Any material depicting or describing the human body or sexual conduct in a way that arouses sexual feelings. This includes scantily dressed women in bikinis, lingerie or revealing clothes, scantily dressed woman in comics, cartoons, or art, erotic books, risky material in movies, TV shows, phone apps, or games.
LDS .org Church Definition of Pornography -
"Pornography is any visual or written medium created with the intent to sexually stimulate. If the work was not intended to stimulate but nevertheless causes sexual arousal in an individual, it constitutes pornography for that person."
&
"Pornography is any entertainment that uses immodest or indecent images to stimulate sexual feelings. So even a mainstream television program or advertisement can be pornographic. If images trigger sexual feelings in you, you should avoid them."
Are there differences
between slip, lapse, & relapse? Yes. Technically.
S.L.I.P -- "Sexual Sobriety Lost its Priority" - A slip is a one-time unexpected unplanned break in abstinence. Slips are
significant events that call for immediate attention. But how can one know it
will truly be the LAST time they will ever act out? For all an addict knows,
they could act out again in a few days, few months, or next year etc. And if
one-time-slips continue to occur, would each one still be considered a
"ONE time unexpected unplanned break in abstinence"?
Relapse - A relapse is the recurrence of symptoms of a disease or to resume addictive
behavior after a period of abstinence.
Lapse - A lapse is somewhere confusingly in between.
