I've been having dry and itchy white skin around the genital area for about a month and I am not sure what is causing it. I am sexually active and my partner has the same symptoms between the thighs and under the scrotum. I couldn't get to a proper diagnosis online, if you have any information please let me know.

We can't diagnose on the internet. You had best make a doctor's visit, both of you to have it properly determined.
