Rashes, Itching, Liquid Discharge. It?

The inner thighs and folds of hips along with the testes showed rashes growing on them. Soon it reached the penis and the foreskin got affected with it. They occassionally itch. Moreover, the itching occurred from about 2weeks ago and the full grown rashes were observed later. They were applied with Ketoconazole soap and an an anti-fungal cream. The skin of the testes seemed to dry a bit days after that. It has been 1week since the antifungal cream is being applied. But today, it suddenly appeared that the rashes(the red spots, some grown, some small yet) reached the bottom part of the penis skin and affected the whole of it. A liquid is being discharged since the body was washed and the cream was applied. Touching the part gives a burning sensation. What can be the possible ailment and what can be done to cure it?
