Are parents to blame?

This was his tweet "some of us grew up without sexual education from our parents and ended up having sex with our siblings. Our generation must do better."

Not a lot of people agreed with him and they fired back with quick responses which all said the same thing "you don't need sex education from your parents to know having sex with your siblings is wrong."

In his Twitter thread @JajaPHD shared screenshots of people who made unverified claims of incest both on a personal level and knowing siblings who did.

The word incest exists because sexual relations between blood relatives happen. Bible scholars can point out to a few cases of incest in the Old Testament. And if you are not into religion at least you watch "Game Of Thrones" and can see freaky things happened between a brother and his sister back in the day.

At the heart of this story is that are we born with the knowledge that incest is bad or is it something that must be taught by parents?

Granted sex education in Nigeria is nothing to write home about. As a young Nigerian, you are expected to figure out hormones and puberty by yourself. The closest you can get to an explanation is when your Biology teacher gets to the Reproduction part of the syllabus.

Our prudish attitude towards sex reflects on issues such as sexual consent, rape, sexual violation amongst others. We don't talk about sex. We just know people have it.

Without sexual education it's hard to believe that some kids do not see incest as a taboo of sorts. Every human being has a moral consciousness, a conscience you might say wired in his or her DNA.

Children know killing is bad because they are born with a moral framework of good and bad. Our parents didn't have to lecture us that killing is wrong. We just know. I would like to believe the same goes with incest.

However, one cannot dismiss the numerous tales of siblings sleeping with each other. There are too many sordid stories of incest on the Internet.

These stories will make you wonder if parents have a role to play so that their children don't engage in incestsexual relationships? In more advanced nations, we have seen cases of brothers and sisters having an affair

What exactly is the reason behind incest, lack of sex education from parents, the devil or a reason that humanity and science haven't figured out yet?
