Thanks for your query at DoctorSpring.com. I can understand your concern.
I appreciate the redness that you mention, however it does not seem due to fungal infection. It seems to be more of an allergy. Allergy to a condom or a lubricant etc. Cortisone cream applied twice a day and a moisturizer applied twice a day should be able to slowly resolve it.
Cortisone is the mildest steroid cream. It will be necessary to treat an allergy.
Please let me know if you have any queries. Take care
