Thanks for posting your query at DoctorSpring.com. I can understand your concern. I reviewed the pictures.
You seem to be having a lot of dry skin. It could be due to an allergy or an eczema with associated yeast infection.
I would recommend an application of cortisone cream mixed with clotrimazole cream twice a day for two weeks.
The allergy could be due to a condom that you might be using. The cortisone cream would take care of any allergy that might be present.
Please let me know if you have any queries. Take care
