Why would you say there's nothing wrong in premarital sex?

If there's nothing wrong, then why the following are considered wrong?



1. Sex outside of marriage
2. Incest
3. Sex with a prostitute or anyone

We can now have protected sex with condoms and if both agree, there shouldn't be anything wrong with the above three.

Sex outside of marriage should be fine if we are having it for fun and we are loyal to our partner. It would be 'conservatism' if our partner still doubt on our love.

Incest. There should be nothing wrong with this if the two agree. We have condoms and we won't have any harmful disease.

Why these all are considered a taboo? If they are a taboo, why premarital sex isn't a taboo?

Please think about it and I hope that you all came to the conclusion that SEX Before Marriage i.e Premarital Sex should be avoided.
