Female sexual partner who remains 'unactive' during lovemaking, physically cold & non-responsive.
Making love with her is no fun at all.She doesn't move or interact at all.She's a coldfish !

A sex partner who is either not receptive, or not providing any emotional or physical feedback during copulation.
Perhaps something was on his mind, but the cold fish watched while I did all the work.
