Doesn't seem to be possible to edit these posts after posting -- the "time out" appears to be immediate. I should have used the intermediate view first. So I apologize for the messed-up quoting in the above reply.
So, to summarize, if there is not a true mutual physical sexual sharing, my experience is that lopsided sexual interactions can just lead to further dislike of physical sex and the feelings about one's partner in that context. If she just pleasures me, she eventually thinks I want it too often, she thinks it's a PITA chore, I think of women as sexually uncaring, not to mention totally sexually unresponsive. I've found it just doesn't work and things are better if we just drop the whole sexual thing between us.
