looking at your chart - my guess is the Gemini rising and pisces moon, then add to that the pluto venus sextile.
Gemini risings are communicative, generally look pretty approachable with the pisces moon and what you said of being supportive. I imagine most people come to you with all their personal dramas/problems. the venus pluto sextile can really tap into underbelly of people's problems, so you probably give great advise and communicate it freely with others. people like that sort of thing.
the scorpio sun might make you a little more selective in who you say what to though.
you've got some nice aspects to venus.. so perhaps that is why you attract womankind more.
just my novice oriented two cents.
