Why do guys give hickeys?

[Anonymous]

Why do guys feel the need to leave hickeys on someone, especially who isn't their girlfriend?
What's the point? lol
Me and this guy where play fighting and he just randomly gave me a hickey, but he sends me mized signals all the time so I don't know how to take it. But i always thought the point of hickeys was to "mark territory?"

Yeah hickeys are usually a sign of marked territory. Some people just enjoy giving them for fun, do not really know why though

Guys are like dogs, they piss on trees to mark their territory. You were just pissed on and marked.
