What Do Boys Gain In A Relationship Without Sex?

I am really asking because i think some Boy's are being used to achieve financial needs.

Take for instance, a student that is probably not going to marry in the next 5yrs.
And he is in a so called relationship that does not involve sex or any romantic activities.
But he spends on her, he takes her out and pay for her private needs.

Let me ask you officially

what do you gain from such a parasitic relationship ?

If you are not into sex, because of religious purpose, then why are you into a relationship?

Why not save the money and give to the orphanage and receive blessings, if you are so
religious?

And for the girls, If you are not ready for sex before marriage, why are you ready for demanding from your boyfriend before marriage?
