Welcome to healthcare magic.
Thank you for your query.

The redness on the shaft of the penis may be due to various causes.

Allergic reaction from a detergent & washing powder is one of the possibilities.The clothes cleaned by these substances, when come into contact with your body, may cause allergic irritation.

Yeast infection should be considered also. It may be transmitted from sexual contact. It may cause similar symptoms described by you. It can be treated with anti-fungal cream.

Lubricating agent used during masturbation may also cause some irritating reaction.

Sexually transmitted disease should also be considered.

It is better to see a physician to get examined and investigated for these causes.
He may prescribe a medicine depending on the cause.

Hope I have helped with your query. Let me know if I can assist you further.
Take care.

Yesterday I got my nexplanon insertet, and today when I removed the bandage around the arm, I notices that the implant has moved around 2 cm up from the insertion point. I can t seem to feel the upper end of the implant, but can see and feel the lower end. Should I be worried about it going in my arm? I can feel probably 3 out of the 4 cm length of the implant. It hurts a bit, but I think it s just from the regular bruising. Not sure if I should check this out or just let it heal (unless the pain doesn t go away).
