12th House Sun Influence for relationship?

Hello all.

Well, my boyfriend has natal sun in the twelfth, I have a natal sun in the twelfth, and our composite is sun in the twelfth. What do you think that could mean?

In the composite chart the sun is sitting in capricorn, ruler of the ascendant conjunct saturn as well as all the other outer planets, lol, that's very weighty for the sun to be conjunct all these planets in the 12th.

Our relationship is sort of private and hidden, and we are both private people, that is the only thing coming to mind about it.

Mathew the Astrologer wrote a great article on composite which makes a lot of sense to me now that I think about it. Check it out...it was referenced in a recent thread on synastry vs composite...

thanks, I will
