What you seem to be saying is that you disagree with the TER scoring system. You wouldn't be the first person to disagree with it! I don't agree with every aspect of it either, but it is what it is. As I said, participation in the TER community is voluntary. But as you know, it's not a democracy.
"Really bi" can certainly apply to a massage session. I've seen many ads for two-woman massages where they say they'll "get it on" with each other during the massage, and I've read some reviews of two-woman (bi) massage sessions. More than one guy? Not sure how that applies to a massage-only session, but that's not in question here, is it?
You wouldn't give a full point for kissing with tongue... ok fine. A lot of guys including me would disagree with you. I guess some of us enjoy that more than others, so giving an extra point for it seems fair.
As for how a FS provider feels when a DIY gal outscores them... maybe they should look at how they approach their business. I've read lots of reviews of FS providers where it's clear it was less than a great session... more like a "slam bam thank you ma'am" kind of thing... mechanical, no connection, no kissing, etc. No wonder some DIY providers outscore some FS providers.
I wonder how a DIY provider feels when she gives exceptional service to her clients within her boundaries, yet some guy rates her only a 6, or even a 7, because he thinks that's the highest score a DIY provider should get? Is that fair, given there's nothing in the TER scoring system that penalizes DIY providers other than they aren't eligible for an extra point for offering a BBBJ, and a point for offering anal sex?
As for the need for a different classification system, consider what the performance rankings mean, from 7 on up:
7 = Hot time
8 = Went the extra mile
9 = Forgot it was a service
10 = Once in a lifetime
Note there is NO mention of the TYPE of service. So it appears you are saying, it's not possible for a DIY provider to give her clients a "hot time". I assure you, that is not the case! You also seem to be saying it's not possible for a DIY provider to "go the extra mile". Again, I have experience to the contrary. As for "forgot it was a service"... yep, that can definitely happen with a DIY provider too, based on my own experience. As for "once in a lifetime"... I haven't rated anyone, regardless of menu, a 10 yet... I believe it really does mean "ONCE in a lifetime". So if I'm lucky, I'll be able to use that rating once--maybe twice if I'm REALLY lucky.

I know some hobbyists use 10s a lot. I scratch my head on that one.
One thing I think would be good to have is a profile selection that indicates "Massage - DIY". Then you and others who don't like DIY sessions can more easily steer clear of them.
