Hey Bobbi,
Yes, I feel you can be assured that you said the right thing in the right time, you were in the moment, so to speak.

If you give me his birth time and where he was born, I will take a look, I'm pretty curious! I'm betting he has some Pluto-Venus contacts, or Pluto Saturn or Pluto-Sun, considering the way he acts out. Pluto rules all things taboo and sexual and is the ruler of Scorpio. Scorpio is a secretive sign and it makes us secretive in the area it falls in our chart (and more so if you are a Scorpion, or Scorpio rising). But he is a Sagi, so ever the optimist, or should be !!

The iceberg thing, I meant more psychologically/metaphorically than actual things he has done that you dont know about, but I guess thats all part of it.

Can I ask you.. you have known him since you were 16, but you two havent ever really discussed (or not properly) his desires in this area, the things he feels compelled to do?
