I Think Tiffany is gorgeous looking and I'd be thrilled if she was still doing porn but the reality is that she's only shot for a couple of studios and the only harcore stuff she did was a couple of videos with her BF. I keep saying that porn isn't for everybody and if you aren't comfortable doing it then move on. Doing something that you don't like is bad enough but having sex in front of a camera when you don't want to must be a 100 times worse.
If Tiffany really wanted to do porn then I'm sure that there are plenty of studios that would have booked her. The old I'm thinking of starting my own site is pure illusion on the part of the model. On those rare case where it isn't then the content isn't worth a dollar. The number of good to better solo model porn sites is miniscule and only those that had already some porn prior to open thei site are usually worth it.
