I'm not sure if you are looking for a provider's opinion or not. Firstly, I am not familiar with the Scribe scale, so forgive me if I should familiarize myself with that first.
As a provider I'm more of the mindset of not discussing what goes on BCD. I'm weighing in merely because I find the OPs views of BLMs interpreted interaction with the ladies to be....not at all how I perceived him in reality. I'm just one person but in my interactions with him I have found him to be kind, funny and naughty.
Clients are all different. Providers are different. Both sides come in with different needs. Variety is good. Personally, due to other real world commitments I gravitate towards shorter sessions. Its not because I don't value myself its because its what my time currently allows and because my fiscal goals are different, so on my side of things --- that may be influencing the clients I gravitate towards. At the end of the day, as long as both sides are having fun in a safe manner, I think its all good.
You do you. Also, stop giving so many fucks about things you shouldn't be giving a fuck about. Save your fucks up for what matters to you.
