Red scaly around genital area

My genital area has been itchy last week, I haven’t checked it since I thought its normal so I scratch it sometimes when its itchy but then after a week the itchiness is still their but its painful so I decided to look at it in the mirror. I saw this red rashes I think? With scaly part. I’m currently taking doxycycline, an antibacterial medicine for my acne and I think it might have contributed to it, so I search about

yeast infection and got a clear picture as an example. I was wondering if this is yeast infection? or not? How can I treat this at home? Is there any home remedies for this? Please help cause I haven’t experienced something like this before
