Hmm... Though it was never my experience with him I think I may understand these 2 criticism even though an explanation would have been better.
Flake: He may have forgotten their appointment because his modeling work is more important to him than this. It may be best to schedule an appointment with him day of or day before and remind him day of appointment.
Not very Pleasant: Without an explanation it is hard to figure out what wasn't pleasant since no 2 persons have the same expectations. I can not speak about if he likes to cuddle or not because I don't request that. However, since I hear on hear a lot that some guys just seem to have trouble taking bigger dicks that maybe where the problem lies. He goes through a bunch of Kama Sutra positions and likes to set the pace he likes. One time he had me doing the downward walking dog . If you need it to be slow your best bet is it ride him otherwise, he will just stop because you cannot keep up.
