That's a good question.
I'm going to be thirty in a few years and I have never really managed to get a girlfriend or even a mere one night stand. The one girl that was my girlfriend - my only girlfriend, friend, all in one, ever - showed up out of nowhere, picked me up and ditched me a year later just as easily.
I swear it's not a looks issue, I don't smell, I don't spit at people while talking with a lisp, I'm well groomed, slender, muscular, etc. . . I'm not hostile, I like to be helpful to both strangers and acquaintances just for the fun of it and I even try to play along when someone tries to small-talk with me.
Yet, people that don't have any of this at least have a girlfriend. Myself, I'm baffled at how people have affairs on top of the relationships they already have when I can't even have a conversation!
Girls on the bus, for example, seem to rather sit besides an old person or remain standing rather than to sit besides me.
Really, I dont know. . . I swear I don't anymore.
Whenever I had acquaintances to go clubbing with nothing much happened - they rarerly picked up anything themselves and I would just stand there and watch.
