I don't really care for having one, but I don't know how to say to people that I haven't because people seem to go crazy when they hear that and I go all shy :(
I wouldn't call myself ugly, but I go to an all girls school so I guess people want to know
MY QUESTION IS: how do you approach people saying that you haven't had a boyfriend?
Thank you!

how do you approach people saying that you haven't had a boyfriend?
People: "You've never had a boyfriend?!"
You: "Ya. What of it?"
People: "It's juss, I dunno."
You: "K. Peace."

Walk away. Done.

Huh? It's actually a good thing that you haven't had one yet and are allowing yourself to mentally and physically mature before getting into the romance drama. You have the advantage over everyone who might look down their nose at you for not having one. Do like slapshot said.

You say you don't have one because you don't want one.
