Games. One does not simply sex, at least for me. Only with the one I love.

Same

Well being asexual really helps in that matter. For me is isn't a very unlogical choice. If you don't have a sex drive you miss the motivation to game or want romance in the first place. So videogames are a pretty obvious choice above sexual activity. But you have to be biologically abnormal I give you that. 

This is like asking someone to choose between Drink or Eat.

Sex. I can always find an alternative to video games.

Well, even that required some form of penetration!

I guess we could call it robotality.

Like so many others it really depends.
Are we talking forever? In that case probably Video Games (your prime years of sexual activity only last so long).
Are we talking just in the moment? If so then sex, I'll take care of my partner then like someone else said once she is asleep then I may go game (if she falls asleep really deeply).

I'm curious do you ever go for longish periods where you abstain from sex (a year or two).  I have gotten bored with partners in the past where I would rather game then play with them.  If I go a good 6 months without nookie though ... I'll likely drop the controller so fast I'd be half naked before it hit the floor. To qualify that I have had a lowish number of partners over the years.  I've only ever done the "one night stand" thing (not that she expected more) once and felt like such a piece of shit afterward that I can't imagine I'd ever do it again.

So, Miguel, which would you choose?
