I'm a Taurus with Gemini Venus trine Ascendant too!
Except my Ascendant is Aquarius.
I think the aspect can make you charming, attractive, and likable. ^^
Since Venus creates harmony with how you express yourself, other people feel that harmony and therefore find you attractive.
The way you present yourself can be seen by others as beautiful.
However, does your Sun square your Ascendant?
Mine does. =\
How that plays out for me is that people see me as a Taurus, but when I express my Aquarius-like quality, they're really shocked!!
It's like having a quiet face with a loud voice....that's exactly me, however since realizing that, I try to control my loudness. xP
Hmm...then again, Libra and Taurus ruling planet are both in Venus, so you probably don't have sun square ascendant....
