Well, here's where we're at now. I'm journaling this simply because I hope everything works out eventually and this will help someone else going through this.
We decided the schedule was great for the past couple of months. Worked well, but feel like we've progressed enough that it's starting to feel too artificial even though it works.
So we've decided to sort of agree that 3 good ML sessions/week is what we're after and are going to work on doing it when we're already having a good night doing something else, try to ride those good feelings into the sack, so to speak. Make things a little more natural.
There are still problems, however. Despite the good efforts and attitudes, her lack of desire is really starting to influence mine. I mean, and sorry if this is too graphic, but like many guys I wake up stiff as a board most mornings, really strong erection. However, once we start going at it, even though she's accommodating, she's clearly not feeling it much, and that's just killing my erections to the point that once we get around to being ready for intercourse (after I've given her the massages, kisses, and plenty of oral), I'm either limp or only semi-hard at best...enough to penetrate, and once that happens, I'm fairly good to go, but occasionally even that gets a little difficult now once we're in the middle of it. I don't lose the erection altogether, but it's definitely affected.
