Why are single men labeled 'losers'?

Isn't this so annoying? If a woman is single, people appreciate her and say things like "she's focusing on her career", "she's waiting for the right man" etc. But if a man is single, he is almost always labeled a "loser" and people believe that he has some serious flaw due to which he is unable to find a partner.

I'm a 28 year old man, University graduate with a reasonably good job. I had been involved in a few relationships earlier (which most people don't know), but I have been single since more than 5 years. Right now, I don't feel that I'm ready for a relationship or even dating. And if I force myself into a relationship just because this stupid society expects me, then I won't be able to do justice to the relationship. It would be totally unfair for me, and even more so for the woman. I'm sick and tired of people asking me "How could you be single for so long?", "When will you introduce us to your special someone?" and even "If you're having trouble finding a girlfriend, I can set you up with someone". Why the hell can't they understand that its MY life and MY choice about when I want to date? Why do they have to poke their nose into my personal matters?

On the other hand, my female cousin who's 26 and single, actually gets so much praise on a daily basis. Everyone lauds her for controlling herself before finding the 'right man'. What the hell.

Its not only about me or my female cousin, but I'm saying in general. So is it mandatory for all adult men to be either in a relationship or married? Don't they have the liberty to remain single until they feel they are ready for a relationship, without every other person saying nasty or irritating stuff about them?
