CIM is nice but most of the time, the BBBJ is foreplay on the way to CFS. If a provider is doing the BBBJ to finish me off, then sure, I'd like her to actually finish. Of course, some providers will pop a cover in her mouth, and convert the BBBJ to CBJ before completion, and that could work too. By that point, I am flexible!
What I have been having a surprisingly (to me) difficult time finding is a provider into...and really mean INTO (not just reluctantly willing to do) the classic GFE activities: DFK (and lots of it) and BBBJ and DATY. Once upon a time, one could find GFE easily. Some AMP providers even happily did this (back before most of the Emerald AMPs were leveled). Now, I run into way too many providers who claim they are GFE, and they will not kiss at all beyond a peck on the lips. I must be looking in the wrong places.
For me, knowing that the provider is passionate about MY presence with her, and not just the presence of my wallet, is critical to whether or not I'll enjoy myself. To me, kissing (and where appropriate, licking and sucking) everywhere on each other's bodies is the prime indicator of passion and desire. Lack of it is a turn off for me.
Oh... and one more thing. Have boobs gotten more sensitive or something? I have a pretty skilled mouth that is good at deep boob sucking massages, and some ladies really enjoy that. However, lately I've run into too many with very sensitive boobs. A Anything beyond licking or VERY light nipple sucking makes them complain about it being too rough. Maybe I've just been catching providers at the wrong hormone levels in their monthly cycle. YMMV, huh?
