Is it normal to give a girl a hickey?

no girl likes purple and black marks on her body

Yes. If she doesn't like it why would you persist in doing it?

Your oral skills should be directed about 2 to 3 feet lower.
Lay off the hickeys. They’re embarrassing on adults in every way possible.

If she isn't into it, no, it's not normal.

Your title and final questions conflict. I answered Normal, in answer to your last question, ease up on the hickeys.

No one older than 14 wants a hickey.

I like them. As long as you're willing to work below the wait too and keep them off my neck and on my chest instead.

I am a man. A woman can put a hickey on me anywhere anytime.

If she doesn't want it then she doesn't want it. She's expressed that clearly.

Depends on the person though. I think it's really hot being branded, scandalous, although I'd wonder how to hide it for work until it disappears. I'd have to have it lower down where it can be covered.

Am I the only adult here that likes getting them? Sure it's embarasing but it's like a symbol of his affection and being his, like yea it's nice

If she doesn't want one don't give her one, my bf 40 loves giving them to me and I live getting them and I'm 20, so yea posy college id say its normal, havent been to collehe yet thoygh, camt afford it yet haha

Hickeys are just as juvenile as ostentatious, prolonged, and very public displays of affection.

Kids wear hickeys proudly because they prove they've made out with someone. No emotionally mature adult feels the need to do that, and if you feel the need to leave your mark on women you're intimate with, then I suggest you take a long look at why that is.
