“The article specifically said that dating other guys should be non-sexual if she’s having sex with her boyfriend.”
Wow, so she’s supposed to go on DATES (but absolutely no sex) with other men while only doing one OTHER guy?
Is she supposed to TELL the other guys, or let them think they have a shot with her?
Come to think of it, the 42nd US president redefined what sex “is” for us.....
Sure. It may sound weird in the abstract, but in practice, it's perfectly normal. Imagine you're out, you meet a woman, and ask her out. She says:
"Look, I've got a boyfriend, but we've been going out for 8 months and he won't commit. So I told him that if another guy asks me out, and I like him, I'm going to say "yes", and see what happens."
Now maybe that would be a turn-off for you, but not for me. Because if you get to the point where you're really hitting it off with the girl, she's going to ditch that other guy.
I don't have a problem with that.
