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 Scorpio in House 11 brings desire, taste, relationship, and attraction into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Scorpio style (intensity, desire, crisis, secrecy, and invisible power); Mars in Leo in House 8 brings action, courage, competition, and effort into House 8 (sexuality, shared power, crisis, and invisible bonds), with Leo style (presence, pride, creation, and the wish to be seen).
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 8 (sexuality, shared power, crisis, and invisible bonds); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
