I'm thinking about sharing a suggestive joke.
Does the joke you're going to tell refer to something in particular?
Yes, to a guy's body parts.
Just make sure you know your audience, because it is impolite to be rude or tell suggestive jokes in public. Some people will be offended, so you need to be careful with what jokes you tell.
I have no idea what you're talking about. It'll be fine.
You may get away with telling a crude joke around some people, but if you tell a joke like that in the wrong crowd then people may think less of you. Just try to be conscientious of who you're joking around with.
