text: why do guys run hot and cold? why do some men (and some women) move between being very warm and intmate towards someone and blanking them totally, for no reason (ie the other person has done nothing to upset them?) as for women - most generally agree that her personal issues need to be met in order to feel free to be intimate.  for instance: rent overdue? child sick? these matters can distract from intimacy, and appear as a cold spell.   for a guy - supposedly we have a comparmentalized psyche that allows us to be romantic even if we just got out of a war zone.  however, harmones ebb and flow, and, if a guy is self concisous about an issue not even related to you, he can appear cold - like his weight may be a little up this morning, or a cut in pay may make him feel less manly and attractive...
