Hi,

Thanks for your query.

Based on your description the rash on the penis head appears probably due to herpes.

Doxycycline is not related to the penile lesion, in fact doxycycline is used to treat many of the sexually transmitted infections.

Do consult a dermatologist to get the lesion examined and rule out the herpes.Meanwhile do apply Ointment Acyclovir twice daily over the lesion.This ointment will contain the infection if it is due to herpes and treat it within few days.

Do not handle the lesion frequently , as it can spread to other parts of the penis.

Hope I answered your query.

Wish you good health.
