Hi,
The most common rash in the penis is caused due to infection:
1.
Fungal infection is very common due to increased moisture and sweating.
2. Bacterial infection can also occur if genitals are not washed properly. genital hygiene is not fallowed.
3. You may be allergic to a particular brand of condom.
4. Baby wipes won't be an issue unless you are allergic to a particular brand of baby wipes.
5. If you have used any drug recently, maybe
drug rash.
6. An autoimmune disorder, the rare condition still need to rule out.
7. If you are with a single partner and use a condom for 2 years every time, is if for
pregnancy prevention? if you had
oral sex, need to think of herpes.
8. Picked up an infection from public toilets
9.
Diabetes can also give you a genital rash if your blood sugar not under control.
Hope I have answered your query. Let me know if I can assist you further.
Take care
