My parents want me to get married at all costs

 For three years, I have not had peace in my life. Everyone, including my parents and my brothers and sisters, insist that I bring a man home. It’s even worse now because they make me feel guilty as if I were a stranger who did something very wrong in her life.
If I ask one of my brothers, help or other things, they say things like “I’m not your husband.” They insult me first then everything else follows.
I am 26 years old and graduated in Computer Engineering. Marriage is not in my mind now, because I am now working on my PhD but no one understands and they do not even want to understand. Most men who are interested in me, I have no feeling or desire for them. So why am I obliged to find a husband?
My job is tedious and takes time especially now with the challenges of the Nigerian economy. Yet my parents say I have to get married.
Please, do you have any advice? One of my colleagues said that I should ignore everyone and continue my life as I want and some say I should just take any man to satisfy society.

I need your ideas please.
