Venus square Mars (orb 0.3°) creates concrete friction between the two planets. The orb is extremely tight; this aspect is one of the chart's strongest signals.
Here, Venus in Leo in House 8 brings desire, taste, relationship, and attraction into House 8 (sexuality, shared power, crisis, and invisible bonds), with Leo style (presence, pride, creation, and the wish to be seen); Mars in Scorpio in House 11 brings action, courage, competition, and effort into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Scorpio style (intensity, desire, crisis, secrecy, and invisible power).
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.
