I am on many sites that you can use as a photographer to contact models, adultfolio is most likely the one where models actually answer your questions.
Apart from direct model to model recommendations this is the best way to arrange photoshoots, all types of models are here, from art-nude to hardcore, so every photographer will find what he is looking for.

My journey on AdultFolio is short but very exciting! I love this website is super easy to use, the booking system is great, all the features are just fantastic! I would recommend it to anyone who works as photographer and a model :)
