Just out of curiosity, how much touch is your wife okay with? Hugging? Kissing? (cheek or lips) Where does she draw the line? Does a handshake make her uncomfortable? or is it just sex itself (and make sure you're both using the same definition for "sex")?
Overall, it sounds like your conversations are progressing, not as fast as you'd like ideally perhaps, but faster than we might have expected.
Love means never having to say, "Put down that meat cleaver!"
