Sleeping around

Okay so, I enjoy having sex. It's fun it's pleasurable. I am sure most of you do too! 
I don't have a boyfriend currently so I have nothing holding me back. So If I go on a "date" or I hang out with someone I find attractive i have no issue with sleeping with them right away. My friend however thinks it means "I'm in a bad place" and I'm slutting around. 
Is this a common opinion? Do you guys agree with her?
