WaryaSimilar situation is happening in UAE - first-cousin marriages. Yes, after few in-breeding seasons many kids come out with hereditary diseases and physical deforms.
Parents/grand-parents are not related. I can't think of anyone in my extended family married to a first/second even third cousins.
But, I gotta be honest. My female first cousins look hot! The type of girls I look for, tall, well-proportioned with long black hair. Let me stop here before I start having nasty thoughts, lol.
Just think of them as your sisters kkk
