I do think the significant observation in this fascinating thread is your rzamataz - that you don't always enjoy his technique.
It looks like a classic failure to comunicate - he thinks the longer he goes on the more you like it, you know that his thinking is off-line but you don't want to upset him.
When you are not enjoying it, why not just say "Kiss me ..." which will bring him back up to you, and you can direct him verbally, or non-verbally, depending how you like to do these things, to move onto something else that you enjoy. Hopefully eventually he will get the message if you do that a few times.
Nice that he is so keen - pity he's not quite so keyed in on female physiology, but at least he's trying, which is more than a lot of other men - right ladies?
