I think this could very well be the reason. Sun, Jupiter and Mars are highly energetic planets so you would emit much of energy, therefore you´d be quickly noticed by others.
Sun conjunct Jupiter can make one "larger that life" character, nearly always in a good mood, with Mars opposing giving him/her a hint of dominance and a bit of commandeering spirit.
This would be especially obvious if these planets are in fire signs, because they naturally rule them. What is your Sun sign?
I have Sun conjunct Asc.
Mars conjunct Asc.
Jupiter sextile Mars.
Jupiter sextile Ascendant.
Also a stellium in the first.
While I have many Capricornian traits(at least on the outside) it seems I don't have that aura.For some weird reason I don't attract guys who have Venus in earth sign.Even if I have both my Venus and Mars in Capricorn.I am attracted to them but they never by me(at least now).Or when they have their sun or moon in earth.It's weird.
Instead this year all I've been attracting have been people with Libra sun/or Asc and always Venus and Mars in Leo.
I guess it plays a major role that my planets are mostly in the 1st.Dunno,I just find it so **** weird.
I've also noticed that I have a hard time getting along with heavily influenced earth/water people.Despite me being all earth and water.We just don't like each other for some reason(at least the girls).
I've also noticed that many of the Arian traits come into surface around the people I am comfortable with.I am loud,very talkative,very restless and fast even competitive and laugh loud too.It's kinda weird.
