Dry red splitting skin on penis

Canesten is the topical thrush cream (anti fungal) brand commonly used within the UK and you don't need a prescription for it. Not sure if it's the same elsewhere

It might be a stubborn yeast infection, or it could just be irritated skin. Another possibility is that you have a sensitivity or an allergy to something that is coming in contact with your penile skin – latex, a laundry detergent or personal cleanser, or some other substance. You might want to think about whether you have changed detergents recently, or you are using a different brand of condom or a new soap. Keep the area clean, but don’t use a harsh soap – rinsing with warm water is usually sufficient. A penis health cream (health professionals recommend Man1 Man Oil) can help to soothe itchy, dry and irritated penis skin with penis-friendly nutrients and moisturizers like Vitamin A and Shea butter.

Dont use E45 its the worse cream to put on its contains lanolin which some people are allergic too! You need a Canisten HC cream its hydrocortizone but apply thinly..hope this helps..oh and you dont need a presciption you can buy over the counter at a chemist.
