Sex before marriage just makes sex fun to singles without any connection.
There is no covenant between them, they are just joined by body and not soul.
Because of that they even have better relationship with their mobile phones than with their partners.
They are connected more to their phones, internet, social media than to their partner.
They can be together without talking with each other, but both busy with their phones.
This is why some go for their phones as soon as they are done having sex.
Whilst others even check their phones for notifications in the middle of the act.
If you are single, nobody is preventing you from having sex, no one is denying you that access.
The problem is the timing. Fall in love, get married before you start having sex for your own good.
