Wow, it's like whoever organized this made sure that every single person that Kurt would never want to talk about sex ed with showed up as an instructor. He's pretty sure that Puck isn't exactly the authority on advice Kurt would need, and he's certainly not about to ask for it.

"Why are you even here?" he asks. "And why on earth would anyone ever think that forcing me to have a chat with you about...about this would be a good idea?"

Yes. This is stupid. So stupid that Puck should be all "Yeah man, I don't really wanna talk about all the gayness and the buttsexing and shit I wish I had a dumpster to toss you in so we don't have to have this talk." Granted, that's not really how Puck is anymore, but Kurt is pretty sure he would rather be in a dumpster than be in this room right now.
