Generally ,the people who enjoy sitting at the computer all they , those that don't enjoy going out in social enviroments are the introverts and the ones that are 'afraid of the world'.
Trust me on that , I'm a computer science student. I get the chance to closely observe this traits on a regular basis.
As far as women go , beautiful ones rarely or never are any of the 2. They get validated and showered with attention constantly , so they have no feeling of inadequacy. They enjoy themselves while out.
5 to 6 years back I used to take refuge in the safe haven of my own room , playing video games all day instead of ever going out(for the exact reasons I just mentioned.I strongly denied it back then,obviously). And when I say all day,I mean all day. Needles to say that those are now what I see as wasted years. Don't get me wrong , there's nothing bad about video games. The bad part is the excessiveness. I still play some retarded games when I hang around skype with my bros and there's nothing better to do ,but don't use it as a refuge to escape the real world. That's when problems start.
So yeah, if social activities wouldn't be fun , people wouldn't do them. You say you don't enjoy those activities , but the truth is you don't enjoy yourself doing them. You feel inadequate because of your social fears and anxieties.
Long story short , if you want beautiful women , you'll be as lucky as winning the lottery to ever find one that will love that you never wanna go out and sit on the laptop all day.
