You might have to try for some ladies - there are loads of single, easy women in SV - at the working friends house there's Monika Morris, Tori Kimura and Madison VanWatson - they're all really easy to make friends with, IIRC Madison and Monika are snobs so a few compliments and they're yours and Tori is in politics and is hard working - so she's an easy target too. Fiona McIrish, Molly French, Zelda Mae and Jamie Jolina are flirty, Agnes Crumplebottom and Blair Wainwright and hopeless romantics. From my experience of playing female sims, its slim pickings as far as the men go. For single men I think you're pretty much limited to the Frio brothers, Iqbal Alvi, Leighton Sekemoto, Gobias Koffi, Christopher Steel and Cyc0n3 Sw0rd - and some of those aren't always single at the start of the game. There are about 15 potential single ladies at the start of the game - some do pair off (I've seen Monika Morris and Tamara Donner sometimes be in relationships)
