Hi, Thanks for the query. I understand your concern. Your symptoms seem to be due to male candidiasis ( fungal infection/ thrush ) This is an infection by fungi affecting head of penis, symptoms are on the glance penis ( inner skin ). More possible in people who do not have circumcision ....as that offers a moist place for bacteria to grow. It is not infection of sperms/ semen....it is just local infection of penis. The itching increases after ejaculation... as some semen comes in contact with the infected part & irritates already affected inner skin to cause more itching. It needs more specific drugs (oral/ fungal ointments ) You don t have results with Betnovate....It is a steroid preparation.. can relieve itching for some time.. but later on tends to help fungi flourish. You can use OTC drug like candid cream locally... iIf no relief consult your family doctor for specific medication. Thanks
