There are many similarities, I agree. But just because your sun sign matches doesn't mean the rest does. I've met people of my own sign whom I perceived to be totally different. On the other hand, I might have been in denial at the time ;-)

Virgos are very meticulate. I've got five planets in Virgo, so I can relate. Most of my long lasting friends happen to be Virgos. The Virgo women I've known are different than the males though. I think the most common thread between Virgo males and women is their meticulessness which *can* drive others crazy. Two of them together might find this to be precious common ground. Just my $0.02.

I think many male Virgos have a lesbian woman inside! At least I have one & I consider myself a REALLY straight guy (I mean really). But I understand woman in ways they perhaps do not really appreciate. I can read them like a map!

Of course being male is going to make the energy different than a female. And it's been said but there are so many other factors... your birth number alone makes a big impression on your sun.

I have a Virgo moon so I'm constantly analyzing emotional things... so I can only imagine what it's like having that as a sun. It's a lot of energy to have. In a number of the Virgos I have been around, more than a few have been manipulative. I wonder why that is.

Ever met a Virgo person with a lot of Uranus/Aquarius influence in their chart? I know two (one male, one female)... they're ridiculously fun people. Highly electric.

And I don't mean to offend anyone... but does anyone notice that "Fat, angry/cynical female Virgo" syndrome? What is that all about? I can't tell you how often I've come across this archetype. Some of the women can come across as angry shrews.

As a Virgo, in answer to the first question

Are male Virgo different from female Virgos?

Even though I believe relying on sun sign descriptions is generic, sometimes it helps to generalize and my answer would have to be yes. Recalling all of the Virgo's I've ever met and known well, I'd have to generalize that the critical nature comes out more in the female Virgo, much more prone to nervousness and worrying. Of course, this is based from a small demographic, so don't take too much offense if you think I'm wrong.

Would this pairing work?

Of course, but other factors come into play, especially which constellation Venus falls in. Myself for example, have Venus in Libra in the eighth house. All of my close friends are fire and air signs and I definitely am much more attracted to and find the company of masculine signs in relationships.

The potential problems in this pairing are the nitpicking that can be engaged in and the moodiness. If each has an understanding of these shortfalls and evolves, then there is a lot of synergy between the two in application of tangible results and aligned interests in the physical world. In bed, I would assume the sex would be great, since the two would have the same razor sharp analysis of what each other likes and dislikes. However, the main obstacle would be the emotional detachment that both are so prone to and selfishness. Serving each other would be key, honesty, and a bit more warmth.
