Venus opposite Mars (orb 1.4°) puts the two planets face to face, with visible back-and-forth or tension. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Venus in Virgo in House 11 brings desire, taste, relationship, and attraction into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Virgo style (precision, method, usefulness, and attention to detail); Mars in Pisces in House 5 brings action, courage, competition, and effort into House 5 (creation, performance, and personal expression), with Pisces style (imagination, faith, compassion, dream, and permeability).
Concrete conflict: this aspect opposes Venus and Mars: the desire for harmony, empathy, and appreciation of the other can clash with impulse, aggression, raw desire, or conflict with the opposite sex. The house conflict is between House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects) and House 5 (creation, performance, and personal expression); pressure in one field tends to reactivate the other.
