Virgo Sun aims to be genuinely good at something useful, and to do it properly; Gemini Moon needs to talk it through, out loud, before knowing what you think. The two signs are three signs apart, which is what decides whether those two agree, and it also tells you the lunar phase you were born under.

Virgo Sun, Gemini Moon: a square, 90 degrees.
The short answerVirgo Sun with Gemini Moon means you are aiming to be genuinely good at something useful, and to do it properly, while needing to talk it through, out loud, before knowing what you think. The two signs are three signs apart, a square, 90 degrees, so the aim and the need pull against each other. It also means you were born somewhere in the last quarter moon part of the cycle.
Virgo Sun: what you are trying to become
The Sun is the aim. Not what you are like, which is a different question, but what you are consciously oriented toward and what you would be proud of being. With the Sun in Virgo that is to be genuinely good at something useful, and to do it properly.
What Virgo quietly takes pride in is competence. At its best this placement becomes somebody things actually depend on, usually unannounced. Virgo is Earth and Mutable, ruled by Mercury, and the recognised weak spot is that it fixes what nobody asked to have fixed.
Gemini Moon: what you need
The Moon is the private half, and it is usually the placement people recognise most sharply once it is described. It covers what you need in order to feel alright and what you do before you have thought about it. With the Moon in Gemini you need to talk it through, out loud, before knowing what you think.
What settles you: conversation, information, something new to be curious about. And the giveaway, the thing people close to you would recognise: talks faster and more when upset, and jokes at exactly the wrong moment. Gemini is Air and Mutable, ruled by Mercury.
What happens when you put the two together
Virgo and Gemini are three signs apart, which is a square, 90 degrees. The friction one. What you are trying to become and what you need in order to feel safe actively pull against each other, so progress tends to cost comfort and comfort tends to cost progress.
Earth and Air are different elements, which is the part that actually produces the mismatch people notice: you are aiming with one kind of energy and recovering with another.

The practical version
Because the two disagree, you will recognise this: the thing you are working toward keeps costing you the thing you need. To be genuinely good at something useful, and to do it properly does not sit comfortably with needing to talk it through, out loud, before knowing what you think, and most people with this combination have arranged their life around the tension without ever naming it.
The useful move is not to pick a side. It is to notice which one you default to when you are tired, because that is almost always the Moon, and to notice what you have been postponing, because that is almost always the Sun.
The phase you were born under
There is a second thing these two placements tell you, and almost nobody mentions it. The distance from the Sun to the Moon, counted forwards, is the lunar phase you were born under. Gemini is 9 signs ahead of Virgo, which puts you in the last quarter moon band.
That is a band rather than a verdict: the exact phase needs the degrees, not just the signs, so somebody at the edge of a sign could land either side of it. What a last quarter moon birth is read as is here, along with the arithmetic to check your own properly.
What this page is missing
Your rising sign, which is what people meet first and which needs a birth time. On any given day, twelve different people share this Sun and Moon and have twelve different rising signs, and they do not come across remotely alike.
Two placements out of about fortyThe Sun and Moon are the two biggest things in a chart and they are still two things. The rising sign, which needs a birth time, is what people meet first and is missing from everything on this page. So is every house, every aspect to anything else, and the whole of Mercury through Pluto. A Sun and Moon reading is a sketch, and a sketch that fits is not evidence of anything beyond the sketch being well drawn.
You aim to be genuinely good at something useful, and to do it properly while needing to talk it through, out loud, before knowing what you think. The two signs are three signs apart, so those pull against each other.
Is Virgo Sun Gemini Moon a good combination?
It is a demanding one, and that is not the same as bad. The friction is what forces people with this combination to examine themselves, which most comfortable combinations never have to.
Do I need my birth time for this?
Not for the Sun. For the Moon, often yes: the Moon changes sign every two and a half days, so anybody born on a day it moved needs a time to be sure.
What lunar phase was I born under?
Gemini is 9 ahead of Virgo, which puts you in the last quarter moon band. The exact phase needs degrees rather than signs.
