I just think they are trashy and dangerous and not a good way to find a partner. I realize some educated people actively pursue causal sex too, but let’s not pretend that we don’t understand or need to mind the emotional and physical health risks of having sex with 30 different people a year, and ignore that this is really unusual behavior that most people don’t do.
We do a really shi-y job some times as practitioners when it comes to discouraging high risk sexual behavior. Sure go nuts and do whatever you want, just use a condom and come in for regular STI screens.
