"Some"? I don't know anyone that wouldn't consider it sexual assault. The proper order of approach begins with eye contact, conversation, and then the touch should begin at the face and shoulder (after kissing) and only then go down. I may be an old person, but as far as I know, it's ALWAYS assault if the FIRST thing you do is put your hand in my crotch or inside my thighs. NO ONE should touch anyone there without either permission or the goddamed preliminars. Maybe I'm old for dating, but I have to yet know the person who went to bed with a man who began the interaction with his hand on the other person's legs. And approaching and saying "come with me to the bathroom" and putting your hands between the other person's legs immediately afterwards is not proper preliminars and should get you slapped.
