The only problem I found in using textual intercourse is that you fill-in the visual gaps and the meeting will reveal the visuals are not automatically what you imagine.

If you were in a singles bar/club or at a dance/festival the visuals would tell you a lot of what you select for. The thing about milling around in a physical environment is that you filter at a distance. With text you begin to form a relationship (at whatever level) before you start to filter. Nothing wrong with that, but you have to acknowledge this. And approach accordingly.
