Step 1: Understanding the Concept:
Every contraceptive method has its own typical complaint. For a barrier method like the condom, problems are almost always local and mechanical, tied to the material against the skin.
Step 2: Key Formula or Approach:
Rule out the systemic or unrelated options first, then pick the one problem that is truly tied to wearing the condom.
Step 3: Detailed Explanation:
Vaginal monilial infection is driven mainly by things like diabetes, antibiotics, or a warm moist environment, not by condom use.
Premature ejaculation has its own psychological and physical causes and is not caused by condoms as a rule.
Retention of urine has no medical link to condom use.
A contact reaction of the skin from the latex or the lubricant/spermicide coating, however, is reported often enough to be called the classic complaint of condom users.
Step 4: Final Answer:
Contact dermatitis is the answer, matching option (C).
