As long as it is done for pleasure and not for procreation, people should do it for pleasure. You know, we can not pretend that we've never had such feelings. The issue is, how do you deal with it.
The common way is that of acknowledging what our customs say about it
The other option can be to do it just for pleasure only and not for procreation.
The debate goes on and so on and so on...
Twenty years ago, when I was considering a relationship with my sister that would have led to a first experience with a loving and patient sexual partner, societal views were so skewed against incest that the very mention was taboo. Today I hope that it will become even more acceptable for consenting adults to engage in this entirely healthy behavior.
Incest between consenting adults should be permitted and excellent expression of love! I don't think the genetic problems are really significant. There is the benefit of keeping the good genetics within the "Family" which in the past some Royal families did. In this country we have freedom. Freedom of expression of love
and sex should be free. Sons in love with Moms, Daughters in love with Dads should have
sex if consensual and of age.. Brother and sister connections are wonderfully satisfying.
As for cousins -- Don't even worry.
Unfortunately the Laws are antiquated.
There are some arguments against this, almost all of which completely flawed.
1) "Deformed children." The risk for deformed children isn't that bad, and the deformities aren't that bad either. Besides, not every incestuous relationship has to do with giving birth.
2) "It's just wrong." This is ridiculous. It's not even a reason.
3) "Personal disgust." That's a reason why YOU wouldn't do it.
4) "There are many people out there, why do you have to have a fam member?" That's like someone coming over to you and your partner/partners and say "Well, there are many other people out there, so, uh, I'm breaking y'all up for no reason."
There are no victims to this crime and governments have no business being in the bedroom. Following the same age of consent laws should be ok except that it would require 18 in the case of consensual incest. The only thing is to criminalize reproduction as it would be a burden on society should difformities occur in offspring.
As an adult you should have the right to decide how to express your sexuality as long as it doesn't infringe on the autonomy or health or someone else. Incestuous sex between adults does not hurt anyone else. There is an issue regarding inbred children, but in this day and age sex can be had for recreation and not reproduction.
No, consenting adults do not have a right to engage in incest, because it is immoral. A society should be allowed to set standards for behavior that it finds acceptable, and if the society decides incest is against its moral standards, the society should be allowed to ban it. In addition, there might be consequences for children born of incest, who are much more likely to have physical and mental problems.
