Venus square Mars (orb 1.6°) 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 8 brings desire, taste, relationship, and attraction into House 8 (sexuality, shared power, crisis, and invisible bonds), with Aries style (initiative, speed, confrontation, and direct action); Mars in Cancer in House 11 brings action, courage, competition, and effort into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), 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 8 (sexuality, shared power, crisis, and invisible bonds) is in friction with House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
