In my opinion, it takes time to know you like and trust each other well enough to start considering the romantic and/or sexual possibilities. I've written a lot about that lately.

That goes counter to the mentality of the Tinder culture, of course, but it doesn't mean I'm not sex positive. I just think it ought to mean something. I can't imagine (for myself, anyway) the thrill of sex with someone who I don't know well enough to call a friend.
