Understanding abnormal stool shapes can provide valuable insights into gastrointestinal health. Based on your description, it seems you are experiencing a mix of normal and abnormal stool characteristics, which can indicate various underlying issues.

Firstly, the fact that your stools start off normal but then become thin and soft suggests a possible issue with the way your intestines are functioning. Normal stool is typically well-formed and cylindrical, while thin or pencil-like stools can be a sign of several conditions, including:
1. Irritable Bowel Syndrome (IBS): This is a common functional gastrointestinal disorder characterized by symptoms such as abdominal pain, bloating, and changes in bowel habits. IBS can lead to alternating patterns of diarrhea and constipation, which might explain the variability in your stool consistency.

2. Obstruction or Stricture: If there is a narrowing in the intestines, possibly due to inflammation, scar tissue, or a mass, it can lead to thinner stools. This is particularly concerning if you also experience pain or discomfort during bowel movements.

3. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation in the gastrointestinal tract, leading to changes in stool shape and consistency. Symptoms often include abdominal pain, diarrhea, and sometimes rectal bleeding.

4. Rectal or Anal Issues: Conditions such as hemorrhoids or anal fissures can cause discomfort and a sensation of incomplete evacuation, which might explain the "hot" feeling you describe. These conditions can also lead to changes in stool shape due to straining during bowel movements.

5. Dietary Factors: Sometimes, changes in diet can lead to variations in stool consistency. A diet low in fiber can result in softer stools, while excessive fiber or certain foods can lead to gas and bloating, affecting how your body processes waste.

The sensation of having to push harder to pass stool, along with the feeling of incomplete evacuation, can also indicate a functional issue with the bowel. This could be related to muscle coordination in the pelvic floor or issues with the nerves that control bowel movements.

Given these possibilities, it is crucial to monitor your symptoms closely. If you notice persistent changes in your stool shape, consistency, or accompanying symptoms such as abdominal pain, blood in the stool, or significant changes in bowel habits, it is advisable to consult a healthcare professional. They may recommend diagnostic tests such as a colonoscopy or imaging studies to evaluate your gastrointestinal tract more thoroughly.

In the meantime, consider maintaining a food diary to track your diet and any correlations with your symptoms. Increasing fiber intake gradually, staying hydrated, and engaging in regular physical activity can also help promote healthy bowel function.

In summary, while occasional changes in stool shape can be normal, persistent abnormalities warrant further investigation to rule out any serious underlying conditions. Seeking medical advice will provide you with a clearer understanding of your gastrointestinal health and appropriate management strategies.
