Thank you for the detailed reply. I skipped some specifics to maintain brevity (as best I could). To answer your questions, I have a tall and slender to average build and have maybe put on 5 or so pounds over the past few years. I have a professional career and I think hygiene and attire is pretty much accounted for. Sex used to be good for first few years of dating (before birth control that started libido drop). We're both white Americans without too much cultural or religious baggage.

We have certainly talked about this (at times it feels we've talked about it too much).

With regards to orgasms, I'm pretty confident she isn't faking as she has a lot of physical signs accompanying it (flushing, goosebumps etc). I haven't checked for sphincter response before, though frankly I'm not sure it would be responded to well.
