The male token answer is to have a Stepford Wife. Which makes your question restricted to only one scenario. That's okay... I'll just reply by saying that an intelligent woman's brain is the sexiest part of her body.

I don't think i would want one of those. ...

Can I have more than one?

I wouldn't create the perfect cyborg mate, even if I was a mad robot scientist who could program such perfection. I'd make her as complicated and crazy and imperfect as I am. A cyborg that trips over itself for no reason. A cyborg that has one too many drinks and pukes in the toilet. A cyborg that has no capacity whatsoever for personal interaction with strangers. A cyborg that laughs at inappropriate dead baby jokes. We are all perfectly imperfect just as we are- why would my cyborg mate be any different?

It's been about 60 years or so since I last made a robot, and all it did was roll forward. It didn't even scare people who rang the doorbell the way a proper robot constructed from an Erection Set by a seven year old was supposed to, so I guess I'm a failure at robot construction.

But if someone were to create my perfect robot mate for me (assuming I found myself single again for whatever reason), I suppose the traits I would look for would be the same I'd look for in a human companion: compassion, consideration, intelligence, and the knowledge and burning desire to make her mate rich beyond his wildest dreams.

A sex robot and a transformer truck.

How would I explain this to my real girlfriend?.

He or she would look like Donnie Wahlberg or Gal Gadot, or I might want 2, one female one male. Hmmmm. He/she would love to travel, go on adventures, love food and be a fantastic chef, be able to hold a conversation, be a good drinking buddy, An amazing kisser, love animals, Know when to give me my own space ( I Guess that is what off switches are for) And be amazing sexually. Open minded, free thinker and an amazing friend.
I may think of something better soon.

I would program it to mimic my personality and emotions etc. Except for anger.

I think my bot would look like Lucy Lu.

Ok you asked

1. Loves themself and has the capacity to love others.

2. Loves animals, music and the outdoors.

3. Wants a long term monogamous relationship.

4. Sexually active, likes physical intimacy.

5. Liberal politically and socially.

6. Enjoys travel and exploring.

Damn, that's deeper than it first appears. I really have to think about what I value in MVSS-O. Independence definitely. A sense of humour, exceptional organisational skills, an overabundance of empathy (makes up for my deficiencies). I'm sure more will occur.
