When you are in high school and talking to your friends about sex, you think its this magical, closest to bliss, act. There is huge thriving sex industry making several hundred billions on this very notion of this copulatory act.
There is nothing wrong with sex, it certainly is awesome, but I think it is over-rated, when compared to pure and simple mastrubation. Here are some of the reasons why
1. You dont have to find a partner, all you need is yourself and some inspiration
2. You dont have to worry about the mood, getting her/him prepared, all of this has its own rush, but one has to agree, that this is probably the only good thing you will miss with a self-satisfying act.
3. You dont have to worry about protection, the only thing you will need will probably be a napkin.
4. No worry about catching some itch, you dont need.
5. You can sleep off right after you finish, you dont have to talk to your partner, this I guess is more applicable to guys.
So, in the long run, I think its quite easy for a person, to live alone, not get into any commitments and have casual one night stands, eat, sleep, drink, enjoy.
There certainly is a category of folks, asexuals, who do not practice sex, apart the more conventional, hetero, homo and bisexuals. Is there one for people who are content with themselves and occasional others? may be ego-sexuals.
