The girls with the best attitudes honestly are the ones who started this as part timers or managed to make a successful transition to such. There are a smattering of agency girls (see: Roxy) that fit this description. The only girls who I have CONSISTENTLY seen that have phenomenal service AND attitude are normally experienced indies. You could get a newbie who is enthusiastic but clueless, or you could get a veteran that knows and goes through all of the motions but is otherwise a dead fish. Indy girls in this realm control their own schedule, usually charge enough to stay at mid-volume at most, and because of this they are usually able to maintain a healthy sexual appetite. They may not get off, they may not REALLY enjoy it, but they problem won’t find it “unenjoyable” - just an “eh” experience.
The real problem lies in finding girls that fit this mold and are are not exorbitantly priced. You’ll have to bump it up to a minimum of 4, most likely 5, to find someone in this ballpark.
