Parents want to meet boyfriend

Okay so a little back story: I'm a 20 year old female and I've never had a boyfriend I still live with my parents and they allow me to do whatever I want. 
My boyfriend lives 3 hours away and we've been dating for 1 year. They want to meet him and my parents claim it's disrespectful that they haven't met him yet. But I personally feel that I don't need to introduce my parents to any guy unless I'm engaged to him.
Any thoughts or opinions would be greatly appreciated. Thank you all in advance !
