Eliza, the "night life" I mentioned consists of multiple same sex partners at a number of well known inner city venues, exactly what CDC are warning against in their fact sheet regarding "open" relationships.

I know of no young heteros who indulge in this sort of behaviour. For some obscure reason, women don't seem to be very partial to group sex with anonymous partners??   Wonder why, is there a difference in how me and women view sex, do you think?
