Did the men experience some type of discoloration due to penile exercising? 

Question 17 asked "After you began penile exercising did your penis discolor? Check all that apply:"

See Figure 1 - Number of Votes:

There were 622 boxes checked. 539 people selected at least one box. The top three answer choices were:

• Yes, the skin tone of my penis is DARKER - 249 votes (46.2 percent)
  
• No, not at all - 204 votes (37.8 percent)
  
• Yes, the skin tone of my penis is more of a BRONZE color - 69 votes

Did a warm-up reduce the darkening effects?

For this analysis, the answer choices were split into two groups.
Group 1 consisted of the men who used a warm up 'most of the time' or 'always'.
Group 2 consisted of the men who 'rarely' or 'never' used a warm up.

• 45.5 percent of the men in yes-warm up group experienced penis darkening.
• 45.8 percent of the men in no-warm up group experienced penis darkening.
• Accordingly, there was no significant difference between the groups that used a warm up and those that did not.
