Candida balantatis. Kindly suggest!

I was having itchy penis with redness for two days with tight foreskin..I have applied alo Vera gel for two days and it become normal and itchiness stopped...but during morning erection some gel remain under glands in tight foreskin. Two days back I had a redness patch on glands and foreskin with little white substance. I applied gel again dint get.much better. I met a dermatologist and he diagonised it as candida balantatis due to fungal and advised me a tablet and onabet cream for two times a day. I applied it for one and half day now..the itching has stopped but the redness as increased and spreading. I washed the are and applied alo Vera gel..it was burning for a while and became normal. Now I am confused to use onabet cream. Kindly suggest
