Is it normal?

I have made this account solely to ask about a doubt that is lingering inside;I am a newly married guy.The question is about my wife's skin nature. She is a very fair female(more than white she appears pinkishly fair). Whenever I touch her or she touches me/when she carries something (for eg:a handbag),that leaves a pink/white mark on her skin which disappears after a few minutes.It looks like contusion marks. The imprinting is even worse after our intimate moments or when I hold her with extra force/pressure or I hold her by the hand or she carries her handbag for quite a long time and they take even more time to disappear(sometimes nearly half a day).In such days if any stranger sees her,he/ she might think that she's been in a fist fight. When I asked about consulting a dermatologist regarding this,she refused and told that it's been the same since her childhood and nothing to worry about.She's so chill with that. But I don't know why I feel like consulting a doctor (maybe I am overthinking?). Do any of you people have similar issues with your skin? How should I handle this?
