I think it's just best people meet and see if chemistry is a go from there. Guys are already aware of menu and stats more or less from guys and a showcase as it is. Should not need too much other info. Maybe a couple pics but nothing crazy. Sometimes I feel women show too much and I talk myself out of it, especially if pics and vids are in reviews.
Back on aspd, I found myself more attracted to girls without pics. I had less bias other than a few reviews saying "you won't be disappointed" and generally was relieved when I saw most women being better than what I was picturing, and sometimes taught myself to just expect the worse kind of mentality.
Now, guys complain all the time about girls not looking better than the pics. Or the photos weren't accurate. In combination of someone who was impressed with a lady in a review and misleading photos, guys are walking in to being let down more lately. But seems to be the vibe I get.
I think of it this way. Girls you meet generally in a public setting you don't have them sending selfies or pics to you before meeting them. That's what a dating site is for.
I personally respect anonymity and meeting with as little info as possible. A brief description, maybe a teaser pic or two, and menu is all I need and usually turns out to be a much better time as I get turned on in person with the lady I am sharing time with. Just my perspective and experience. And with that, I've also opened myself to more women than I otherwise would have. Huge confidence booster which has helped talk to girls in general as I used to be very socially awkward.
As for girls getting pics of us, that's up to the lady really. Probably best to be surprised all the same as one pic might lead to all kinds of bias without meeting a guy first which could lead to less than stellar service. The fact a guy is turned on to see you should get the motor running in itself and turned on upon arrival. Same principle really, can expect the worse and anything better is a go!
After meeting a lady a few times, and if a good relationship starts, exchanging pics can be a fun thing to do, but I wouldn't do it until I get to know someone. We are only handles until then.
