Wanting and Liking: Why BFPAs Can Keep You Coming Back

If you've ever found yourself engaging in a body focused process addiction (BFPA) even though you didn't really want to do it—or continuing long after it stopped feeling good—you've experienced an important distinction: wanting and liking are not the same thing.

We tend to assume that if we do something repeatedly, it must be because we enjoy it. But the brain is more complicated than that. A behavior can become something we strongly want to do even when we don't particularly like doing it anymore. This distinction may help explain why BFPAs such as hair pulling, skin picking, nail biting, or other repetitive body-focused behaviors can feel so difficult to resist.

Two systems, not one

Think about two overlapping but different experiences:

Liking is the pleasure, satisfaction, relief, or sensory reward that comes from the behavior.

Wanting is the urge to pursue the behavior—the feeling of I need to do this or I have to fix this spot or just one more.

Most of the time, wanting and liking show up together. If something feels good, we want more of it. But with repetitive behaviors, these two systems can gradually separate. You may begin with a behavior that provides something genuinely rewarding: relief from tension, a satisfying sensation, the feeling of removing an imperfection, or simply a pleasant sensory experience. Over time, however, the behavior can become increasingly automatic and cue-driven. You may still experience a strong urge to do it even when you already know how it will end.

The behavior is wanted, but not necessarily liked.

BFPAs can also become closely connected to particular internal and external cues. Maybe you notice a rough patch of skin. You feel a particular texture. You catch yourself in the mirror. You experience boredom, stress, frustration, or fatigue. You sit down to watch television. Your fingers begin searching almost before you've consciously decided to do anything.

These cues essentially prime the behavior. The cue doesn't have to be a conscious thought such as I want to pick. Sometimes the urge seems to arrive first, with the explanation coming afterward. And once the behavior begins, the sensory experience or emotional shift that follows can strengthen the connection between the cue and the behavior.

The brain learns, in effect:

Cue → urge → behavior → consequence.

The consequence might be pleasure. It might be relief. It might be a sense of completion. It might simply be a change in an uncomfortable internal state. Whatever the payoff, the brain has learned something important: this behavior does something for me.

The crossover: wanting more, liking less

Here's where things get especially interesting. With repeated BFPAs, wanting can remain strong even when liking decreases.

You might pick at your skin for several minutes and eventually think, Why am I still doing this? You might pull a hair and immediately regret it. You might bite your nails until they're sore and still find yourself putting your fingers back in your mouth.

The behavior may no longer be particularly pleasurable. In fact, it may produce pain, frustration, embarrassment, damage, or regret. And yet the urge persists.

This is one reason that simply telling someone to "stop" rarely captures the complexity of BFPAs. The person may not actually be choosing between doing something enjoyable and not doing something enjoyable. They may be experiencing a powerful learned response toward a behavior that no longer provides much pleasure at all.

One of the most useful things to remember is that an urge is not a command. The experience of wanting can be intense, but it is not necessarily permanent. Urges rise, peak, change, and eventually decrease—even when we don't act on them.

That gives us another option besides the familiar pattern of:

urge → behavior

We can create a little space:

urge → pause → choice

The goal isn't necessarily to make the urge disappear. Trying desperately to eliminate an urge can sometimes make us even more focused on it. Instead, the goal can be much smaller:

Don't feed the urge for the next few minutes.

Change what your hands are doing. Get up. Move to another room. Put on something that occupies your fingers. Hold something with an interesting texture. Take a few slow breaths. Put a barrier between yourself and the usual target. Engage your attention somewhere else. These strategies aren't about proving that you have enough willpower to "beat" the urge. They're about giving the brain an opportunity to learn something new: an urge can show up without automatically getting what it asks for.

The bigger picture: changing your relationship with the urge

Understanding the difference between wanting and liking can also change how we think about setbacks. If you engage in a BFPA after successfully resisting for a while, it doesn't mean you've failed or that all of your progress has been erased. It means an old, well-practiced learning pattern was activated. Instead of asking:

"Why couldn't I control myself?"

it can be more helpful to ask:

"What triggered the urge? What was I hoping the behavior would do for me? What was happening before, during, and after the urge?"

Those questions can provide much more useful information. They help us understand the function of the behavior rather than simply judging it. BFPAs aren't just about whether we enjoy the behavior. They're influenced by a combination of learning, cues, urges, sensory experiences, emotions, habits, and reinforcement. Understanding these pieces gives us more opportunities to interrupt the cycle and respond differently when the urge shows up.
