I believe the morality factor comes in as; the knowledge of the family member & how they may be related.

I have seen 20/20 where a brother & sister met as a couple and did not know they were in fact siblings since one was given away at birth. They had to have their marriage annulled & have agreed to never reproduce; more so due to the genetics. These were two random strangers who met, fell in love, no one knew until after the wedding a few years later.

Those who are cousins, even first, through marriage alone...no true bloodlines crossing; in fact are strangers if raised without being so personal. I have a first cousin, did not know, had a crush on him as a kid, and yet we had no genetic ties...we found we were only cousins through a marriage. Wrong? Too close for comfort, we were kids, and it was always a crush until we found out we were related.

Nowadays we have reformed family's. Both parents marry with children about 6-10 y/o. Now, let them hit puberty & dating? Although, they are not blood related it causes issues in the household since there is generally a Male/female attraction to those you live with yet have no relation other than marriage to.

Parents & siblings with same blood lines? Sorry, sick to me. Very sick to me. I love my brother dearly & would do anything for him; however, any movement beyond a "Brotherly" hug is just gross, much less engaging in sex. And he is a good looking man but he is my brother who I can talk to about sex; had to have the talk with him when he was 15 [since my parents would not] and to date if I am involved with someone he knows yet does not want to hear any vague details if I had a question. The extent of "sex talk" is related to me saying have a great b-day or anniversary & his response being...I am not getting any! Or me asking him a specific question about men in general. But he would never tell me in his opinion "what a man wants & how"...he would freak out.

Having sex with direct blood lines is, well; pretty sick. A distant relative you had no contact with? I can see a sexual attraction initially but not wishing to act on it in reality--thoughts are to keep in your own mind. Meaning you see your older mother's Aunt which you have no real contact with; may find her looking hot, but acting on the actions? NO WAY!

The brother & sister thing to me from the other poster is well...very disturbing. One, they are relatives so close in genetics. Two, are in fact having an affair while not being truthful with their spouses. Three, just too close as a family unit since the correct dynamics are mentally warped. I honestly find this to be a form of a mental illness since the family unit was established and the boundry's are not maintained.
