I can feel my gf's adams apple if i squeeze hard enough

Bet you failed biology
Both female n males have it.
Its just more prominent in men

Why are you squeezing her Adams apple? Are you violent?

Doing that could damage her Adam's apple. Don't do it! There are better ways to find out that both men and women have one.
Like the internet, a book, asking a friend who is a doctor, or is studying medicine...

In men it's more pronounced. In most women it's not visible.

If you're into choking, you should look into the dangers of this. Contrary to what some people want to believe, there's no safe way of doing it.

The Adam's apple is cartilage surrounding the larynx, and both men and women have one. The cartilage is usually more noticeable in men, but some women have a visible one as well.

Why are you squeezing her neck, you jerkwad?

Queeze your own Eve’s apple weirdo.

Don't

Not cool.
Not gonna preach.
But for me, that's a huge turn off.
