Blood fetish is a versatile thing. Not only does it have alternative names - ‘vampire fetish’, ‘haematolagnia’ and ‘haematophilia’ – it's also a sort of umbrella fetish, under which similar yet different blood-loving groups can gather with like-minded people.

For some it takes nothing more than a drip of claret down some stranger’s pert flesh to get them going; others need their beloved writhing in pools of the stuff before they feel that special tingle.

But quantity isn’t the only variable. There are the lickers and drinkers, who, although a minority, are probably a bit cooler than the people on the other side of the ‘ingest or not ingest’ debate.
