Get your self clinically examined.
Thanks for writing your query.
After reading your post, I would like to advise that you should get yourself clinically examined and investigated.
Redness on the penis can be due to cellulitis
which can be treated by antibiotics and anti inflammatory medicines.
The cause of incontinence
and erectile dysfunction
should be known.
It can be due to nerve disorder.
Following investigations may be helpful :-
1. MRI of Lumbosacral spine.
of KUB region.
3. Complete Blood Count
( CBC ).
4. Urine examination.
You should maintain hygiene of the pelvic area.
I hope this is helpful to you.
If you have any further query, I will be happy to help.
