I don't think "all of the above" would've quite worked for me. All except for "enhancement/ supplement to a human relationship" and "artificial companion (I see my doll as a replacement for a normal interactive human relationship)". Although admittedly, excluding the latter could just be denial on my part. I continually put off looking into having a vasectomy, not because I have doubts about not wanting children (I really, truly don't), but because I wonder if it's worth having (slightly) risky elective surgery whose results I'll probably never need.
I chose "surrogate partner (helping to fill the void until ms/mr right comes along)". While the other reasons apply as well (save for the two I mentioned above), this was my
primary reason. I've said innumerable times that I'm just a lonely romantic idealist who, despite being very socially active, has never been particularly lucky in love. And the resulting complications from Ana's arrival only prove that it's genuine, rather than a subconscious ruse based on the assumption that no woman would ever have sex with me unless she was inexplicably in love.
Perhaps the wording should have been "until
and if ms/mr right comes along". 'Cause it seems that every time I meet a woman my species, she turns out to be my long-lost sister. It's like, "Great, I've found my future best woman, now if only I could find my future
bride...."

Not that I don't value my female friends, but why is the chemical trigger only set off by women who are completely wrong for me? Of course it's moot, since 95% of them don't desire me back, anyway. How sick is that, that I'd've preferred a series of flaky and/or psycho girlfriends to perpetual rejection? I want to agree with you, blindwebster, about not giving up who I am in a vain attempt to make someone else happy. But sometimes I feel like I'd gladly sell my soul, only no one's buying...
Edit: I'm not actually as bummed out as I sound in this post, at least not at the moment.

I
can be a bit of a drama king at times.
