This is absolutely about things getting physical in a relationship.
"we can signify our love now" -- as in consummate.
"you can initiate an impulse of love" i.e. an erection.
The entire second stanza is about the sex act itself, and the wonderful third stanza (which, in purely musical terms is one of my all-time favorites from the T Heads, and on the album segues right into "Take Me To the River") conveys that marvelous sense of being in that connected moment with your lover as you build and feel so together.
