Personally I was reluctant to have my face pic out there when I first joined, and still am somewhat so... obviously many people get why some WGs feel this way.
In my first week or two on AW, there were no face pics and no PG (my public photos are hi-res, accurate and recent and give a good idea of me overall)... I ended up naively swapping my face pic with someone who ended up to be a total timewaster ("I don't find you attractive, but want to get your services for free" was the sum of the interaction lol). For now, this leaves me reluctant to provide face pics free of charge or at a particularly low price as I do ideally only want the people I meet to know my face.
However I've had some longer bookings from people who specifically suggested I put my face pics on private, at up to 5 credits for the day. As my intention isn't to generate an additional source of income, rather to discourage timewasters and fantasists (who in my limited experience are less likely to spend money in their strange long-winded efforts) I have 5 non-nude face pictures in my PG for 3 credits for 3 days (plainly stated on my profile and in the captions). Some may consider this too high, I understand it limits me somewhat, but not having it limited me even more and it works well for me. I make between 9 and 15 credits a day, fund my number/availability/local search from this and most of my longer and advance bookings come from people who paid to view them.
Anyway, I think so long as you're honest about what's in your gallery on your profile, have decent accurate and obviously unedited photos... and you're not trying to be a shyster constantly directing people to your PG, you will make enough to fund your daily AW expenses and probably transfer a bit out each month too. I can manage this with non-nude, if you have nude ones I'm sure you can make more and get a better response.
I read both SAAFE and UKP. I have posted more on here, once or twice on there. I find each forum to be the polar opposite, with not enough prominent posters taking the middle ground. Maybe it's because I'm still quite new, but SAAFE's jaded and almost needy tone isn't for me. Although it has some useful info on genuinely dangerous people. I have fun with things so look for some humour in the discussion of the punting/escorting world. UKP can be amusing. However sometimes I find the way WGs are generalized on UKP to be a tad mean (forgetting the reviews which are always going to pop up somewhere if not here). However I was aware of this before joining, having used both forums as a roadmap starting up as an indie. So I lurk and post when I think I have something useful to contribute from "the other side".
I was surprised to see this thread, on UKP not SAAFE anyway, just reminds me of girls asking how much they should charge
