How to introduce my partner to my family?

My family knows I'm gay and while they aren't hateful, they pretend like I'm not gay and ask when I'm going to date someone of the opposite sex and stuff like that even when they know I've been in same sex relationships.I've recently entered into a serious relationship and I don't know how to introduce my partner without making things weird.As in introvert I find it hard to talk about myself and I'm a giant ball of anxiety about almost everything so this is really freaking me out.
