Thank you there l'll get help.
Hi there!
Lack of care while having sex can lead to dryness of the skin around the penis.The penis has many nerve endings and capillaries making it more susceptible for dryness and other problems. Lack of adequate lubrication, rubbing the penis against clothing all can lead to these problems. Allergies, dermatitis, psoariasis and eczema all can lead to dry skin of the penis.Lichen planus is other possibility which causes appearance of scaly flakes and flat topped papules. It is best to get evaluated by a local health care provider. I do hope it helps.
Take care and regards!
