Honest question, I'm really curious: why blood relationship matters in homosexual relantionships?
Correct me if I got it wrong but do you mean blood relationship as in like, siblings? This is just my personal thoughts but maybe because even if it is a homosexual relationship, it is still considered as blasphemous like it is in a hetero relationship. Any homosexual person is still a normal human being. So think about it, isn't it quite strange to have a relationship with someone who you share a blood with? Unless they're one of the greek gods or something. (I'm not mocking the greek gods, don't attack me please) â•®(￣▽￣)â•
From my personal point of view it's more strange to have relationship with family member, rather than with someone you are sharing blood.
But it's only true for homosexsual relationships, heterosexual are different because of possible pregnancy and childbirth.
"incest!" it's not they're not related by blood and tbh this is more like childhood friends to lovers since their ages are not that different.
