Recurring vaginal fungal infection.

I am suffering from some kind of genital infection, me and my partner both got this infection after we used a lubricating gel for the first time. The infected area is around our genitals, the area get bumps initially and then turns red with itching and then dry scaly skin appears. We have been taking itraconazole and fexofenadine tablets since last one month. But as soon as we stop the medicines, it reoccurs even with a little sweat and increses during night. The itchy patches are similar to scabies(just saw the picture and could relate more to this condition) My partner got this infection extended upto his waistline which later got well but near the genitals it is still the same. I do have vaginal discharge at times but minimal and odorless in white color and thick. Can you please help me out with this.
