Great responses by Fun4Her and Lifestyle duo. We agree with everything they both said.
We've only encountered one couple who we would consider to be pic collectors. We chatted with them over , and sent them some full body fully-clothed pics with our faces. They asked for more, so we sent a few more -- our clothes were on, but the pics give you an idea of exactly what we look like and our body type. Finally the couple said they weren't interested and stopped communicating because we did not send any nudes.
I assume now they were only interested in messaging us for pics for their personal spank bank.
We have some sexy photos of us on this site, but we never take nude action pics where you can see our faces. We are a private couple and don't want to risk the photos ended up online somewhere.
