This is simply the conclusion of the entire lyrics. What this couple is experimenting is not a simple love nor the madness. Their love is madness and the singer has realized about that. Their love is just too strong and crazy to let it go, he/she needs love.
For me, this line sensitize in a way the overall meaning of this song, which I'd define as sexy, provocative plenty of lust music. Get up and commit! Show me your energy, do not be any passive, try and do your disclose desires and fantasies. .
