Yes, definitely, but there are elements to this that you have to understand. If you have Sun-Moon or something with her, but she has a Moon-Mercury aspect with another person and you don't, they may be more conversational than you with more overlapping interests and thus be able to charm her on one level more quickly. Any spell can break through this however. Even directing orgasm energy with enough witchpower is VERY POWERFUL.
In my experience, Sun-Moon, Moons in the same place, Mars-Venus and Moon-Venus, plus any of these planets in each other's 1st, 7th or 5th House, are the strongest testimonies for love and sexuality in synastry. These don't necessarily always make for good conversation however like with Mercury, and bad aspects often exist in relationships even with these present. It all has to be taken into account. The parallel/declinating aspects of planets can also be powerful here.
