I've had a few relationships and lot of one-night stands when I was younger.
But how things are now I'll probably end up forever alone. Looks aside I've not met a female thats not taken and whos even relatievely interesting as a person. And who would like me as I am. I'm a quite easy-going, fun loving but quite lazy and flegmatic/apathic person.
And I have no plans in engaging in a relationship just for the sake of having a girlfriend. There needs to be something in her that makes me interested at an intellectual level.
That being said, I cant even get them one-night-stands anymore but thats more about me gaining weight and becoming hairy. And my one-night standards still being in "2006" is a slight problem as well. But thats my own fault and no I cannot really do anything about it.
And well, stopping being an arrogant douchebag probably has some effect as well. And not really liking going out anymore as I did more than enough of that during my younger years.
Here's a picture for reference....
