AdultFolio is a fantastic website for photographers and models interested in more erotic work to get together to collaborate.

I've met and worked with some amazing models from this site and shared and built relationships with wonderful photographers on here as well.

Adultfolio has by far been the greatest platform for me to meet people and gain work from, the site layout is intuitive and easy to understand as is the messaging and media manager side of things.
There are plenty of members and the forum is fun and helpful.
