Yes.
But my close ones have learned to accept my self imposed loneliness. Note that this loneliness from other people is a choice, i still want a relationship with a girl, but that is different.
I actually like being alone. I used to live with my parents for many years and when i got the opportunity i jumped out quickly. I communicate with my friends through facebook and i lay in bed all day watching series on DVD, playing games or browsing the net. I haven't gone out with friends (social drinking) for years, i miss hanging with my friends out on some place, but i have never liked being in a bar with 500 other people, it is not only stressful - i find that social interaction boring. Besides, bars are not exactly full of mensa candidates, and being hit on by a woman who wants to know what star-sign i am isn't something i miss.
Being asocial is a problem that can drive some people nuts, for others solitude is a long sought after privilege.
