Not even a tingle.
Some asexual types understand that refusing to partner up can lead to the type of social stigma that could even undermine their career efforts.
They tend to partner up with other asexuals or become "beards" for closeted gays.
I've considered this type of relationship myself.
Yes, sometimes "beards" get rare passing urges. That's why I'm an all-or-nothing-in-a-relationship kind of person. Shit gets too complicated without consistency.
I think I can appreciate haart's viewpoint, here. She's just too busy with her career to bother.
