Relations with the Penny T\'Soni (Mass Effect 2)

The topic is the bearded Bayan - I know, but I have some specific questions, and read hundreds of comments not very desirable.
So, start from the beginning.
When passing the first part I made out with Penny and all. Due to the fact that the character I liked in itself - he decided to run ahead of the engine - got on the Mass Effect Wiki to read that with the Penny shines on. And then I a little too was unpleasantly surprised - the Penny in the second part happening the menstrual cycle and post-menstrual syndrome because of the Grey Mediator, and turn the hurdy-gurdy in the second part I fail. Although on the page http://ru.masseffect.wikia.com/wiki/Любовь drawn that in the second part, Liara still available for a relationship.
Actually, here I applied for resolving incompatible information that I have. What do you say about this ?

My personal Infostrait other relationship I'm not interested in principle, because I can see and on our planet (and maybe participate, so nothing unusual).
As for variance - external view (without the mask) and the history of this character makes me nauseous (literally).
If the dead take into account the fact that I play Shepard-a woman - that the appearance of Garrus Vakarian I have the same disgusted in terms of a relationship with him. As for the story - it's not as bad as with karenkay. Lol.
And with the passage of the mission on Vamire I was puzzled by the choice of who to keep - Ashley Williams or Kaidan of alenko. When I searched for information and tips - accidentally discovered (all on the same page about love for the Mass Effect Wiki) that in the third part of alenco Cayden gay; after I learned this - do not hesitate to leave it on Vamire. I wonder what happened to him in the explosion, which was sickly seen from orbit ? And the question is not about death, but about in which direction and how fast scattered protons and electrons of its atoms ...
