First I'd attract her by turning my skin into some different colours, really get her into the show. Strobes, blinks, synchronized flashes; women love light shows, no exceptions. Next I'd twist my body into some different shapes, shove myself under a rock or something that'd be pretty based. Once she shows her satisfaction by chittering with her weird octopus tooth, I'd get so close that our tentacles were practically touching, inching closer and closer. The flare of my strobing skin would drown everything else out as my two front tentacles start intertwining with hers. I'd promise her the best rock in the ocean as our den, and the finest pearls and glittering stones her gifts. Then, right before our bulbous heads would meet, I'd ink all over the place then run away; I'm not that easy. Nice try, lady.
Actually though, recognize that it's awkward for everybody involved and especially the first time. And don't put on an act or anything like that, its impossible to keep up long term and probably not hard to see through.
