@ Harbinger265: Well, you made a counter-claim and you waited for my opinion... there is "decency" on the forum outside of the admins.

I really don't think Tali would've necessarily been allowed to go on her pilgrimage while maintaining her virginity. Surely she had to have been intrigued or pressured to screw one of her own kind before she left. I think the Quarian philosophy is that they only start to become adults once they leave on their pilgrimage.

Another realistic reason is that the ships in the Migrant Fleet have a highly-sterile environment, free of germs and other contaminants. So I don't see a reason why she wouldn't have a one-night stand, rather than a relationship of some sort.

Lastly, it could just be that because of what Quarians are known for, they (including Tali) are somewhat ashamed of delving into their past, so maybe she is concealing a previous relationship from Shepard, especially if it went sour.

One thing's for sure though, and Harbinger hit it bang on, that Shepard was her first Human sexual experience.
