Haven't posted for a couple of days, so much to catch up on but I'm going to focus on you jesuis for a moment as he sounds very familiar :)
As I often say this is just me and not representative, but on my first 4 dates with MissOz I was on my best reserved behaviour. After date 4 things got a bit wierd, which I've already posted about, and we had quite an open honest conversation and have moved on well (so far).
Since we got back on track I have relaxed massively, I'm not trying so hard now, and the fun flirty personality she saw in my messaging (sound familar) is now materialising IRL.
She has far more experience in the bedroom department than I do (my marriage had a very vanilla sex life which has dented my confidence in taking control) but I'm now finding the confidence to lead as well as follow if that makes sense.
I suppose what I'm trying to say is that with somebody encouraging, supportive and willing to lead my true self (maybe one I didn't even know was there) is starting to flourish.
Give him a chance and be willing to take the lead, he might surprise you ;) MissOz said she worried I was "too nice" for her in the first few dates, 7 dates in that is no longer a concern.
Don't get me wrong you might need or want somebody different, apparently I'm refreshing after a very dominating ex so it works for us, but give it a chance would be my recommendation. There may be more under the surface than you realise, just needs a bit of encouragement ;)
Tl;dr give him time
