What happens when Venus and Mars are conjunct in the 7th house for Gemini Ascendant? Is love marriage indicated?

The presence of Mars and Venus combo in the 7th house of marriage is not favorable in your case. Natural malefic Mars, the evil lord of the 6th and 11th houses, conjunct with Venus, the lord of the 12th house of loss, may together undermine your marital life.

Love marriage may be possible because of the presence of the 5th lord of romance, Venus, in the 7th house.
