Sex Terms Help!!

Lily
Okay - this is really embarrassing for me - I need some help with sexual terms. I'm a junior in high school, and I feel so lost when people say stuff and then everyone laughs. This site is also pretty confusing because it uses stuff and then I end up sitting around going "what?"
Plz help! Think of any and all things plz!!! I feel so awkward!😬😜🤓😕
