Totally disagree here. And yes, I got the warning from phone girl telling me to be super careful with japanese woman (x3).
I think that if the sex sucks that both parties are at fault. I also think if one party is properly skilled it is pretty darn impossible to have bad sex.
All the bad sessions/sex I had in this hobby have been my own fault. It was me that had the bad day. Even if the girl is tired and having a bad day all it takes is a little bit of charisma and being nice to get the girl in a better mood.
But I'd add that sometimes, it's just the chemistry. Frankly, in large measure due to sites like these, I rarely have a "bad" session in which I'm thinking, "jeez, what makes you think that you should be doing this job." More often, it may be disappointing from my expectations going in, which is on me.
There are so many things that go into whether a session will be great or "just OK." But sometimes, it is the gal, even with a regular. There's a regular I see in CT for massage and BBBJ. When she's on, man she's great. Fairly often though, she's just OK but there was one time when she was clearly distracted with something going on personally and texting throughout the massage. Then she left the room for about 20 minutes without much explanation. Comes back and gives me a full on, high energy DT and CIM. If I had that one session as my first, I definitely would have never returned and would have given her a bad review.
