Sometimes used as a euphemism for having sex with someone as for example in
Bob Welch's song
Ebony Eyes:
Cause if I had my way with you baby
I would be changing your life today
Or in the song
I'd really love to see you tonight by
England Dan & John Ford Coley:
I'm not talking 'bout moving in
And I don't want to change your life
But there's a warm wind blowing
The stars are out
And I'd really love to see you tonight
