Hell no. I've been in 2 relationships, one lasting a couple months in high school which barely even counts and the current one which just passed the 2 year mark. The one I'm in I'm feeling pretty confident about but if it doesn't work out I'd never do it again. The girl I'm with now was my best friend beforehand. I found her attractive, but she didn't sleep around so I figured I wouldn't even try anything. SHE asked ME out which is the only reason I even considered it, and even then I didn't expect it to actually work out in any capacity. I figured I'd give it a shot, maybe we'd last a week or two, I'd have a nice little reminder of why I don't date, and I'd move on with it.
I wouldn't say it's changed my perspective though. In that case there was an emotional connection already, but I'd never go out of my way to try to create one. I feel like any sense of satisfaction I get from the companionship is because of the specific person I'm with, not because I like companionship in general. Even with her, whenever I have to obligationally bite the bullet and do courtship things it's pretty painful. (I'm currently working on a machine that will create a black hole which will forever remove February 14th from existence.)
But anyways, really long answer for no. If this relationship doesn't work out that's it. If I feel lonely I'll get a dog. And if I need to have sex I'll fuck the dog go to a bar and treat some skank with low self esteem like I'm better than her.
