I am an Aquarius as well. We certainly are the adventurous, wild, free-spirit type
Astrology fascinates me as well, and I have asked some clients here and there what their sign was (after a session) just to get an idea. I try not to ask beforehand.
I wouldn't reject a client just because of his sign, but here is a couple of experiences I remember...
I met a Leo....Saw him 3+ times. Last meet, he was very possessive, almost didn't let me leave while blocking the door trying to get me to stay...Never saw again.
Met a Scorpio...Interestingly have some intellectual things in common, but sex was very blank and disconnected. We clicked in non-sex stuff.
I would love to meet a Gemini!
(If I haven't already, lol)
