So I had another interesting session last night. I was only somewhat aroused. So it wasn't as intense as other sessions have been. What I found, is that I can't get anything out of the Peridise if I am not extremely aroused. I guess you can't really force the issue with these models, as you can to a certain extent with the prostrate massager models. So basically I had to go back and forth between the Progasm and Peridise models....
