It's about stage appearance and allowing yourself to be visible. Dig in to every single note you play. Know your songs. Look confident. Dress confidently. Look at the girls at the shows, not at neck of your bass or on a lead (cheat) sheet on the floor. Show you're having a good time on stage.
Know the songs in and out. Play basslines that stands out, groove and fit the music. Play a cool bass solo perhaps once or twice during a concert. I know a few girls that think bass solos are the coolest ones.
