do my placements make me unemotional?

sun/moon: gemini
sag rising
aries venus
gemini mars
taurus mercury
I don't find myself that emotional, but what do you think?

Whats the rest of your placements? Lacking water in the chart doesn't exactly make you un-emotional, but you would generally be a more logical and rational person, who might lack a little sensitivity. You have a hard skin and don't grieve with anything.

But if you have a strong moon, pluto or neptune, many 4th, 8th or 12th house planets, you can make up for you lack of water.

I think it is a bit rare that a person has a completely lack of any water, but it does happen.
I lack fire in my chart for an example, because I don't have any fire planets, and I only got venus and pluto in 5th house.

But because I got Sun conjunction Mars and some other strong mars aspects, it gives me a little of that fire I lack.

So I could imagine that if you got a conjunction to your moon, from sun, pluto, neptune or venus, you would have a better contact with your feelings.
