Venus square Mars (orb 1.7°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Venus in Aries in House 11 brings desire, taste, relationship, and attraction into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Aries style (initiative, speed, confrontation, and direct action); Mars in Cancer in House 2 brings action, courage, competition, and effort into House 2 (resources, values, and security), with Cancer style (memory, protection, belonging, and family sensitivity).
Concrete friction: this aspect creates tension between attraction, pleasure, empathy, and direct action: the person may alternate between seducing, appreciating the other, attacking, desiring, or turning relationship into a power struggle. House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects) is in friction with House 2 (resources, values, and security); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
