Oh yeah, I agree she's using it as an excuse to even bring it up. I wonder how self-conscious Philip would be if she got to a place where she pushed a little and it became clear that she really wanted that from him. Because I think their sexual relationship has been screwed up in a lot of ways over the years, but they've been strong enough to get past separation, betrayal of trust, infidelity on both sides, one of them potentially dying or being captured... I think Philip could get into it, particularly if Elizabeth were encouraging him as they went along and he knew it was mutually being enjoyed.
