The good news
Of men with severe size anxiety show reliable improvement after twelve weeks.
Veale et al. 2019, randomised controlled trial, n = 102 — Body Image. "Reliable improvement" follows the Jacobson reliable-change index used across the body-image literature.
The three techniques
What actually works, drawn from CBT body-image research.
01
Fix your thinking.
Wrong thought. "Everyone else is bigger."
Reality. The population mean is 13.1 cm — you almost certainly are within one standard deviation of it. Write the worry down, write the evidence, observe how the worry softens once it is on paper. This is a CBT thought-record exercise.
02
Stop checking and comparing.
Compulsive measuring, comparing in locker rooms, and consuming pornography all reinforce the cycle. Each comparison is biased upward — never against the median.
- Stop measuring constantly.
- Avoid porn — it shows the largest 1%.
- Do not compare in locker rooms or to friends.
Track the reduction in checking behaviour weekly. Most men report relief within four weeks.
03
Talk to your partner.
Most men never ask their partner what they actually think. When they do, partners' answers cluster overwhelmingly around "I am fine with your size; I worry about other things."
This single conversation often produces the largest single drop in anxiety reported in the clinical literature.
How fast it improves
The shape of the recovery curve.
Week 01 – 02Learn the real numbers.Most relief comes from simply seeing the data. Roughly half of men feel meaningfully better in the first two weeks.
Week 03 – 06Practise the new thinking.The CBT thought-records become automatic. Checking behaviour drops by half on average.
Week 07 – 12Stop worrying entirely.7 in 10 men report no further size-related worry by week twelve, in the Veale RCT and the Wylie self-help replication.
Self-help works
65% recovery rate in a self-help-only cohort.
Wylie and colleagues replicated the Veale RCT with a non-clinical online cohort of 58 men using only a self-help workbook — no therapist contact. 65% of participants stopped worrying entirely by the end of the programme. The number is not as high as the clinician-led trial, but it is the same direction of effect, and it is available to anyone with an internet connection.

When to talk to a clinician
If size worry is affecting your daily life, consider speaking to a therapist who specialises in body image, or to a CBT clinician. The self-help workbook is in the appendix of Veale 2019 and is freely available online.
