Is that indicated in my chart?
Interracial or intercultural dating/marriage might not seem all that unconventional to someone of your generation, but some people forget that it's only been within living memory that such relationships have even been
legal in most parts of this country (never mind considered socially acceptable) -- and unfortunately, there are a few places left in this country where they're still not socially acceptable.
I can only speak for myself...but I think the fact that your Venus is in the sign of Sagittarius potentially might be one indicator of your interest in an interracial (or rather intercultural) relationship. When one or more of the inner planets -- Sun, Moon, Mars, Venus -- or a significant point in a person's chart (Ascendant) falls in Sagittarius, interest in other cultures is often indicated. My own Ascendant is in Sagittarius, and most of my romantic partners have been born outside of the US. (I think the fact that I spent three years living overseas as a child also has something to do with this.) I also see that your Mercury is in Aquarius, which like Sagittarius is a sign which rules the collective. Aquarius is ruled by Uranus and as such is progressive and a bit rebellious in its mindset. Mercury is not considered as important as the other inner planets when it comes to estimating synastry -- but the fact that you have your Mercury there suggests that you're inclined to be open-minded and unconventional despite your Sun in Capricorn and your Moon in Taurus (Earth signs tend to be very conventional). I notice that your Mercury is the only Air planet in your natal chart, making it a singleton -- so your Mercury has more influence over you than it ordinarily would. It forms a very nice sextile with your Venus and Jupiter as well, suggesting that your intellectual needs are in harmony with your ideals and your concept of beauty (although it does clash with your Mars). I also notice that your Sun and Moon both form positive aspects with your Uranus, suggesting that you're inclined to question tradition -- even though your Sun and Moon are in Earth signs. Moon sextile Uranus suggests that you're very tolerant of differences, which lends itself well to an intercultural relationship. Venus also forms a fairly close conjunction with Pluto in your chart, suggesting that you're looking for a relationship with a lot of intensity which will have a transforming impact on you and/or your partner...and certainly, one way to challenge and transform yourself is to date/marry someone who's very different from yourself (such as someone from another culture).
Since you're already on Astro, I would recalculate your natal chart in order to find out where the asteroid Juno is located. The placement of Juno in the natal chart, whether by sign or by house, can sometimes provide clues regarding the kind of person someone would consider an ideal spouse. If Juno is in Sagittarius or Aquarius, that would also suggest to me someone who has a strong interest in dating outside his or her own race or culture. When Juno is in Sagittarius, this desire is more reflective of the interest in and fascination with other cultures specifically. When Juno is in Aquarius, this desire is more reflective of a more general interest in progressive or unconventional relationships. (That being said, Juno in Aquarius might be so interested in progressive relationships that they either might feel no need to be married at all in the traditional sense or might be drawn toward the idea of an open marriage.) If Juno is located in your ninth house (the house ruled by Sagittarius) or the eleventh house (the house ruled by Aquarius), I think this might also play a role in your interest in interracial or intercultural relationships. My Juno is in Libra, but it's in my eleventh house -- in my case, my ideal partner is someone who's my friend as well as my lover but I also have somewhat unconventional attitudes about marriage. Also, with my Juno in an Air sign located in an Air house, the last thing I want is a spouse who's going to wrap himself around my ankles metaphorically speaking (although my Venus square Uranus has a lot to do with this).
