Is there another way of writing this in a 15 year old boy way?

Question

Their love is pure rather than forced by physical, desire, lust or money grabbing.

i don't know how to write this in a easier way for someone like me to understand.

'Their love is pure rather than forced' this bit is alright but i don't know how to change 'by physical, desire, lust or money grabbing.'

please help me.

Answer 1

Their love is pure and unfettered by physical or financial motives.
